+# `eslint-plugin-react-hooks`
+
+This ESLint plugin enforces the [Rules of Hooks](https://react.dev/reference/rules/rules-of-hooks).
+
+It is a part of the [Hooks API](https://react.dev/reference/react/hooks) for React.
+
+## Installation
+
+**Note: If you're using Create React App, please use `react-scripts` >= 3 instead of adding it directly.**
+
+Assuming you already have ESLint installed, run:
+
+```sh
+# npm
+npm install eslint-plugin-react-hooks --save-dev
+
+# yarn
+yarn add eslint-plugin-react-hooks --dev
+```
+
+### Legacy Config (.eslintrc)
+
+If you are still using ESLint below 9.0.0, please continue to use `recommended-legacy`. To avoid breaking changes, we still support `recommended` as well, but note that this will be changed to alias the flat recommended config in v6.
+
+```js
+{
+  "extends": [
+    // ...
+    "plugin:react-hooks/recommended-legacy"
+  ]
+}
+```
+
+### Flat Config (eslint.config.js)
+
+For [ESLint 9.0.0 and above](https://eslint.org/blog/2024/04/eslint-v9.0.0-released/) users, add the `recommended-latest` config.
+
+```js
+import reactHooks from 'eslint-plugin-react-hooks';
+
+export default [
+  // ...
+  reactHooks.configs['recommended-latest'],
+];
+```
+
+### Custom Configuration
+
+If you want more fine-grained configuration, you can instead add a snippet like this to your ESLint configuration file:
+
+#### Legacy Config (.eslintrc)
+
+```js
+{
+  "plugins": [
+    // ...
+    "react-hooks"
+  ],
+  "rules": {
+    // ...
+    "react-hooks/rules-of-hooks": "error",
+    "react-hooks/exhaustive-deps": "warn"
+  }
+}
+```
+
+#### Flat Config (eslint.config.js)
+
+```js
+import reactHooks from 'eslint-plugin-react-hooks';
+
+export default [
+  {
+    files: ['**/*.{js,jsx}'],
+    plugins: { 'react-hooks': reactHooks },
+    // ...
+    rules: {
+      'react-hooks/rules-of-hooks': 'error',
+      'react-hooks/exhaustive-deps': 'warn',
+    }
+  },
+];
+```
+
+## Advanced Configuration
+
+`exhaustive-deps` can be configured to validate dependencies of custom Hooks with the `additionalHooks` option.
+This option accepts a regex to match the names of custom Hooks that have dependencies.
+
+```js
+{
+  "rules": {
+    // ...
+    "react-hooks/exhaustive-deps": ["warn", {
+      "additionalHooks": "(useMyCustomHook|useMyOtherCustomHook)"
+    }]
+  }
+}
+```
+
+We suggest to use this option **very sparingly, if at all**. Generally saying, we recommend most custom Hooks to not use the dependencies argument, and instead provide a higher-level API that is more focused around a specific use case.
+
+## Valid and Invalid Examples
+
+Please refer to the [Rules of Hooks](https://react.dev/reference/rules/rules-of-hooks) documentation to learn more about this rule.

+semver(1) -- The semantic versioner for npm
+===========================================
+
+## Install
+
+```bash
+npm install semver
+````
+
+## Usage
+
+As a node module:
+
+```js
+const semver = require('semver')
+
+semver.valid('1.2.3') // '1.2.3'
+semver.valid('a.b.c') // null
+semver.clean('  =v1.2.3   ') // '1.2.3'
+semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
+semver.gt('1.2.3', '9.8.7') // false
+semver.lt('1.2.3', '9.8.7') // true
+semver.minVersion('>=1.0.0') // '1.0.0'
+semver.valid(semver.coerce('v2')) // '2.0.0'
+semver.valid(semver.coerce('42.6.7.9.3-alpha')) // '42.6.7'
+```
+
+As a command-line utility:
+
+```
+$ semver -h
+
+A JavaScript implementation of the https://semver.org/ specification
+Copyright Isaac Z. Schlueter
+
+Usage: semver [options] <version> [<version> [...]]
+Prints valid versions sorted by SemVer precedence
+
+Options:
+-r --range <range>
+        Print versions that match the specified range.
+
+-i --increment [<level>]
+        Increment a version by the specified level.  Level can
+        be one of: major, minor, patch, premajor, preminor,
+        prepatch, or prerelease.  Default level is 'patch'.
+        Only one version may be specified.
+
+--preid <identifier>
+        Identifier to be used to prefix premajor, preminor,
+        prepatch or prerelease version increments.
+
+-l --loose
+        Interpret versions and ranges loosely
+
+-p --include-prerelease
+        Always include prerelease versions in range matching
+
+-c --coerce
+        Coerce a string into SemVer if possible
+        (does not imply --loose)
+
+--rtl
+        Coerce version strings right to left
+
+--ltr
+        Coerce version strings left to right (default)
+
+Program exits successfully if any valid version satisfies
+all supplied ranges, and prints all satisfying versions.
+
+If no satisfying versions are found, then exits failure.
+
+Versions are printed in ascending order, so supplying
+multiple versions to the utility will just sort them.
+```
+
+## Versions
+
+A "version" is described by the `v2.0.0` specification found at
+<https://semver.org/>.
+
+A leading `"="` or `"v"` character is stripped off and ignored.
+
+## Ranges
+
+A `version range` is a set of `comparators` which specify versions
+that satisfy the range.
+
+A `comparator` is composed of an `operator` and a `version`.  The set
+of primitive `operators` is:
+
+* `<` Less than
+* `<=` Less than or equal to
+* `>` Greater than
+* `>=` Greater than or equal to
+* `=` Equal.  If no operator is specified, then equality is assumed,
+  so this operator is optional, but MAY be included.
+
+For example, the comparator `>=1.2.7` would match the versions
+`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
+or `1.1.0`.
+
+Comparators can be joined by whitespace to form a `comparator set`,
+which is satisfied by the **intersection** of all of the comparators
+it includes.
+
+A range is composed of one or more comparator sets, joined by `||`.  A
+version matches a range if and only if every comparator in at least
+one of the `||`-separated comparator sets is satisfied by the version.
+
+For example, the range `>=1.2.7 <1.3.0` would match the versions
+`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
+or `1.1.0`.
+
+The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
+`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
+
+### Prerelease Tags
+
+If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
+it will only be allowed to satisfy comparator sets if at least one
+comparator with the same `[major, minor, patch]` tuple also has a
+prerelease tag.
+
+For example, the range `>1.2.3-alpha.3` would be allowed to match the
+version `1.2.3-alpha.7`, but it would *not* be satisfied by
+`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
+than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
+range only accepts prerelease tags on the `1.2.3` version.  The
+version `3.4.5` *would* satisfy the range, because it does not have a
+prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
+
+The purpose for this behavior is twofold.  First, prerelease versions
+frequently are updated very quickly, and contain many breaking changes
+that are (by the author's design) not yet fit for public consumption.
+Therefore, by default, they are excluded from range matching
+semantics.
+
+Second, a user who has opted into using a prerelease version has
+clearly indicated the intent to use *that specific* set of
+alpha/beta/rc versions.  By including a prerelease tag in the range,
+the user is indicating that they are aware of the risk.  However, it
+is still not appropriate to assume that they have opted into taking a
+similar risk on the *next* set of prerelease versions.
+
+Note that this behavior can be suppressed (treating all prerelease
+versions as if they were normal versions, for the purpose of range
+matching) by setting the `includePrerelease` flag on the options
+object to any
+[functions](https://github.com/npm/node-semver#functions) that do
+range matching.
+
+#### Prerelease Identifiers
+
+The method `.inc` takes an additional `identifier` string argument that
+will append the value of the string as a prerelease identifier:
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta')
+// '1.2.4-beta.0'
+```
+
+command-line example:
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta
+1.2.4-beta.0
+```
+
+Which then can be used to increment further:
+
+```bash
+$ semver 1.2.4-beta.0 -i prerelease
+1.2.4-beta.1
+```
+
+### Advanced Range Syntax
+
+Advanced range syntax desugars to primitive comparators in
+deterministic ways.
+
+Advanced ranges may be combined in the same way as primitive
+comparators using white space or `||`.
+
+#### Hyphen Ranges `X.Y.Z - A.B.C`
+
+Specifies an inclusive set.
+
+* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
+
+If a partial version is provided as the first version in the inclusive
+range, then the missing pieces are replaced with zeroes.
+
+* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
+
+If a partial version is provided as the second version in the
+inclusive range, then all versions that start with the supplied parts
+of the tuple are accepted, but nothing that would be greater than the
+provided tuple parts.
+
+* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
+* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
+
+#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
+
+Any of `X`, `x`, or `*` may be used to "stand in" for one of the
+numeric values in the `[major, minor, patch]` tuple.
+
+* `*` := `>=0.0.0` (Any version satisfies)
+* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
+* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
+
+A partial version range is treated as an X-Range, so the special
+character is in fact optional.
+
+* `""` (empty string) := `*` := `>=0.0.0`
+* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
+* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
+
+#### Tilde Ranges `~1.2.3` `~1.2` `~1`
+
+Allows patch-level changes if a minor version is specified on the
+comparator.  Allows minor-level changes if not.
+
+* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
+* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
+* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
+* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
+* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
+* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
+* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+
+#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
+
+Allows changes that do not modify the left-most non-zero element in the
+`[major, minor, patch]` tuple.  In other words, this allows patch and
+minor updates for versions `1.0.0` and above, patch updates for
+versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
+
+Many authors treat a `0.x` version as if the `x` were the major
+"breaking-change" indicator.
+
+Caret ranges are ideal when an author may make breaking changes
+between `0.2.4` and `0.3.0` releases, which is a common practice.
+However, it presumes that there will *not* be breaking changes between
+`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
+additive (but non-breaking), according to commonly observed practices.
+
+* `^1.2.3` := `>=1.2.3 <2.0.0`
+* `^0.2.3` := `>=0.2.3 <0.3.0`
+* `^0.0.3` := `>=0.0.3 <0.0.4`
+* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4`  Note that prereleases in the
+  `0.0.3` version *only* will be allowed, if they are greater than or
+  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
+
+When parsing caret ranges, a missing `patch` value desugars to the
+number `0`, but will allow flexibility within that value, even if the
+major and minor versions are both `0`.
+
+* `^1.2.x` := `>=1.2.0 <2.0.0`
+* `^0.0.x` := `>=0.0.0 <0.1.0`
+* `^0.0` := `>=0.0.0 <0.1.0`
+
+A missing `minor` and `patch` values will desugar to zero, but also
+allow flexibility within those values, even if the major version is
+zero.
+
+* `^1.x` := `>=1.0.0 <2.0.0`
+* `^0.x` := `>=0.0.0 <1.0.0`
+
+### Range Grammar
+
+Putting all this together, here is a Backus-Naur grammar for ranges,
+for the benefit of parser authors:
+
+```bnf
+range-set  ::= range ( logical-or range ) *
+logical-or ::= ( ' ' ) * '||' ( ' ' ) *
+range      ::= hyphen | simple ( ' ' simple ) * | ''
+hyphen     ::= partial ' - ' partial
+simple     ::= primitive | partial | tilde | caret
+primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' ) partial
+partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
+xr         ::= 'x' | 'X' | '*' | nr
+nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
+tilde      ::= '~' partial
+caret      ::= '^' partial
+qualifier  ::= ( '-' pre )? ( '+' build )?
+pre        ::= parts
+build      ::= parts
+parts      ::= part ( '.' part ) *
+part       ::= nr | [-0-9A-Za-z]+
+```
+
+## Functions
+
+All methods and classes take a final `options` object argument.  All
+options in this object are `false` by default.  The options supported
+are:
+
+- `loose`  Be more forgiving about not-quite-valid semver strings.
+  (Any resulting output will always be 100% strict compliant, of
+  course.)  For backwards compatibility reasons, if the `options`
+  argument is a boolean value instead of an object, it is interpreted
+  to be the `loose` param.
+- `includePrerelease`  Set to suppress the [default
+  behavior](https://github.com/npm/node-semver#prerelease-tags) of
+  excluding prerelease tagged versions from ranges unless they are
+  explicitly opted into.
+
+Strict-mode Comparators and Ranges will be strict about the SemVer
+strings that they parse.
+
+* `valid(v)`: Return the parsed version, or null if it's not valid.
+* `inc(v, release)`: Return the version incremented by the release
+  type (`major`,   `premajor`, `minor`, `preminor`, `patch`,
+  `prepatch`, or `prerelease`), or null if it's not valid
+  * `premajor` in one call will bump the version up to the next major
+    version and down to a prerelease of that major version.
+    `preminor`, and `prepatch` work the same way.
+  * If called from a non-prerelease version, the `prerelease` will work the
+    same as `prepatch`. It increments the patch version, then makes a
+    prerelease. If the input version is already a prerelease it simply
+    increments it.
+* `prerelease(v)`: Returns an array of prerelease components, or null
+  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
+* `major(v)`: Return the major version number.
+* `minor(v)`: Return the minor version number.
+* `patch(v)`: Return the patch version number.
+* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
+  or comparators intersect.
+* `parse(v)`: Attempt to parse a string as a semantic version, returning either
+  a `SemVer` object or `null`.
+
+### Comparison
+
+* `gt(v1, v2)`: `v1 > v2`
+* `gte(v1, v2)`: `v1 >= v2`
+* `lt(v1, v2)`: `v1 < v2`
+* `lte(v1, v2)`: `v1 <= v2`
+* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
+  even if they're not the exact same string.  You already know how to
+  compare strings.
+* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
+* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
+  the corresponding function above.  `"==="` and `"!=="` do simple
+  string comparison, but are included for completeness.  Throws if an
+  invalid comparison string is provided.
+* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `rcompare(v1, v2)`: The reverse of compare.  Sorts an array of versions
+  in descending order when passed to `Array.sort()`.
+* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions
+  are equal.  Sorts in ascending order if passed to `Array.sort()`.
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `diff(v1, v2)`: Returns difference between two versions by the release type
+  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
+  or null if the versions are the same.
+
+### Comparators
+
+* `intersects(comparator)`: Return true if the comparators intersect
+
+### Ranges
+
+* `validRange(range)`: Return the valid range or null if it's not valid
+* `satisfies(version, range)`: Return true if the version satisfies the
+  range.
+* `maxSatisfying(versions, range)`: Return the highest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minSatisfying(versions, range)`: Return the lowest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minVersion(range)`: Return the lowest version that can possibly match
+  the given range.
+* `gtr(version, range)`: Return `true` if version is greater than all the
+  versions possible in the range.
+* `ltr(version, range)`: Return `true` if version is less than all the
+  versions possible in the range.
+* `outside(version, range, hilo)`: Return true if the version is outside
+  the bounds of the range in either the high or low direction.  The
+  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
+  the function called by `gtr` and `ltr`.)
+* `intersects(range)`: Return true if any of the ranges comparators intersect
+
+Note that, since ranges may be non-contiguous, a version might not be
+greater than a range, less than a range, *or* satisfy a range!  For
+example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
+until `2.0.0`, so the version `1.2.10` would not be greater than the
+range (because `2.0.1` satisfies, which is higher), nor less than the
+range (since `1.2.8` satisfies, which is lower), and it also does not
+satisfy the range.
+
+If you want to know if a version satisfies or does not satisfy a
+range, use the `satisfies(version, range)` function.
+
+### Coercion
+
+* `coerce(version, options)`: Coerces a string to semver if possible
+
+This aims to provide a very forgiving translation of a non-semver string to
+semver. It looks for the first digit in a string, and consumes all
+remaining characters which satisfy at least a partial semver (e.g., `1`,
+`1.2`, `1.2.3`) up to the max permitted length (256 characters).  Longer
+versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`).  All
+surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes
+`3.4.0`).  Only text which lacks digits will fail coercion (`version one`
+is not valid).  The maximum  length for any semver component considered for
+coercion is 16 characters; longer components will be ignored
+(`10000000000000000.4.7.4` becomes `4.7.4`).  The maximum value for any
+semver component is `Integer.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value
+components are invalid (`9999999999999999.4.7.4` is likely invalid).
+
+If the `options.rtl` flag is set, then `coerce` will return the right-most
+coercible tuple that does not share an ending index with a longer coercible
+tuple.  For example, `1.2.3.4` will return `2.3.4` in rtl mode, not
+`4.0.0`.  `1.2.3/4` will return `4.0.0`, because the `4` is not a part of
+any other overlapping SemVer tuple.
+
+### Clean
+
+* `clean(version)`: Clean a string to be a valid semver if possible
+
+This will return a cleaned and trimmed semver version. If the provided version is not valid a null will be returned. This does not work for ranges. 
+
+ex.
+* `s.clean(' = v 2.1.5foo')`: `null`
+* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'`
+* `s.clean(' = v 2.1.5-foo')`: `null`
+* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'`
+* `s.clean('=v2.1.5')`: `'2.1.5'`
+* `s.clean('  =v2.1.5')`: `2.1.5`
+* `s.clean('      2.1.5   ')`: `'2.1.5'`
+* `s.clean('~1.0.0')`: `null`

+# ESLint Scope
+
+ESLint Scope is the [ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm) scope analyzer used in ESLint. It is a fork of [escope](http://github.com/estools/escope).
+
+## Install
+
+```
+npm i eslint-scope --save
+```
+
+## 📖 Usage
+
+To use in an ESM file:
+
+```js
+import * as eslintScope from 'eslint-scope';
+```
+
+To use in a CommonJS file:
+
+```js
+const eslintScope = require('eslint-scope');
+```
+
+In order to analyze scope, you'll need to have an [ESTree](https://github.com/estree/estree) compliant AST structure to run it on. The primary method is `eslintScope.analyze()`, which takes two arguments:
+
+1. `ast` - the ESTree-compliant AST structure to analyze.
+2. `options` (optional) - Options to adjust how the scope is analyzed, including:
+  * `ignoreEval` (default: `false`) - Set to `true` to ignore all `eval()` calls (which would normally create scopes).
+  * `nodejsScope` (default: `false`) - Set to `true` to create a top-level function scope needed for CommonJS evaluation.
+  * `impliedStrict` (default: `false`) - Set to `true` to evaluate the code in strict mode even outside of modules and without `"use strict"`.
+  * `ecmaVersion` (default: `5`) - The version of ECMAScript to use to evaluate the code.
+  * `sourceType` (default: `"script"`) - The type of JavaScript file to evaluate. Change to `"module"` for ECMAScript module code.
+  * `childVisitorKeys` (default: `null`) - An object with visitor key information (like [`eslint-visitor-keys`](https://github.com/eslint/js/tree/main/packages/eslint-visitor-keys)). Without this, `eslint-scope` finds child nodes to visit algorithmically. Providing this option is a performance enhancement.
+  * `fallback` (default: `"iteration"`) - The strategy to use when `childVisitorKeys` is not specified. May be a function.
+  * `jsx` (default: `false`) - Enables the tracking of JSX components as variable references.
+
+Example:
+
+```js
+import * as eslintScope from 'eslint-scope';
+import * as espree from 'espree';
+import estraverse from 'estraverse';
+
+const options = {
+    ecmaVersion: 2022,
+    sourceType: "module"
+};
+
+const ast = espree.parse(code, { range: true, ...options });
+const scopeManager = eslintScope.analyze(ast, options);
+
+const currentScope = scopeManager.acquire(ast);   // global scope
+
+estraverse.traverse(ast, {
+    enter (node, parent) {
+        // do stuff
+
+        if (/Function/.test(node.type)) {
+            currentScope = scopeManager.acquire(node);  // get current function scope
+        }
+    },
+    leave(node, parent) {
+        if (/Function/.test(node.type)) {
+            currentScope = currentScope.upper;  // set to parent scope
+        }
+
+        // do stuff
+    }
+});
+```
+
+## API
+
+The following section describes the API for this package. You can also read [the docs](https://eslint.org/docs/latest/extend/scope-manager-interface).
+
+### ScopeManager
+
+The `ScopeManager` class is at the core of eslint-scope and is returned when you call `eslintScope.analyze()`. It manages all scopes in a given AST.
+
+#### Properties
+
+- `scopes` - An array of all scopes.
+- `globalScope` - Reference to the global scope.
+
+#### Methods
+
+- **`acquire(node, inner)`**
+  Acquires the appropriate scope for a given node.
+  - `node` - The AST node to acquire the scope from.
+  - `inner` - Optional boolean. When `true`, returns the innermost scope, otherwise returns the outermost scope. Default is `false`.
+  - Returns: The acquired scope or `null` if no scope is found.
+
+- **`acquireAll(node)`**
+  Acquires all scopes for a given node.
+  - `node` - The AST node to acquire scopes from.
+  - Returns: An array of scopes or `undefined` if none are found.
+
+- **`release(node, inner)`**
+  Returns the upper scope for a given node.
+  - `node` - The AST node to release.
+  - `inner` - Optional boolean. When `true`, returns the innermost upper scope, otherwise returns the outermost upper scope. Default is `false`.
+  - Returns: The upper scope or `null` if no upper scope exists.
+
+- **`getDeclaredVariables(node)`**
+  Get variables that are declared by the node.
+  - `node` - The AST node to get declarations from.
+  - Returns: An array of variable objects declared by the node. If the node doesn't declare any variables, it returns an empty array.
+
+- **`isGlobalReturn()`**
+  Determines if the global return statement should be allowed.
+  - Returns: `true` if the global return is enabled.
+
+- **`isModule()`**
+  Checks if the code should be handled as an ECMAScript module.
+  - Returns: `true` if the sourceType is "module".
+
+- **`isImpliedStrict()`**
+  Checks if implied strict mode is enabled.
+  - Returns: `true` if implied strict mode is enabled.
+
+- **`isStrictModeSupported()`**
+  Checks if strict mode is supported based on ECMAScript version.
+  - Returns: `true` if the ECMAScript version supports strict mode.
+
+### Scope Objects
+
+Scopes returned by the ScopeManager methods have the following properties:
+
+- `type` - The type of scope (e.g., "function", "block", "global").
+- `variables` - Array of variables declared in this scope.
+- `set` - A Map of variable names to Variable objects for variables declared in this scope.
+- `references` - Array of references in this scope.
+- `through` - Array of references in this scope and its child scopes that aren't resolved in this scope or its child scopes.
+- `variableScope` - Reference to the closest variable scope.
+- `upper` - Reference to the parent scope.
+- `childScopes` - Array of child scopes.
+- `block` - The AST node that created this scope.
+
+### GlobalScope
+
+The `GlobalScope` class is a specialized scope representing the global execution context. It extends the base `Scope` class with additional functionality for handling implicitly defined global variables.
+
+#### Properties
+
+- **`implicit`** - Tracks implicitly defined global variables (those used without declaration).
+  - `set` - A Map of variable names to Variable objects for implicitly defined globals.
+  - `variables` - Array of implicit global Variable objects.
+  - `left` - Array of References that need to be linked to the variable they refer to.
+
+### Variable Objects
+
+Each variable object has the following properties:
+
+- `name` - The variable name.
+- `identifiers` - Array of identifier nodes declaring this variable.
+- `references` - Array of references to this variable.
+- `defs` - Array of definition objects for this variable.
+- `scope` - The scope object where this variable is defined.

+# eslint-visitor-keys
+
+[![npm version](https://img.shields.io/npm/v/eslint-visitor-keys.svg)](https://www.npmjs.com/package/eslint-visitor-keys)
+[![Downloads/month](https://img.shields.io/npm/dm/eslint-visitor-keys.svg)](http://www.npmtrends.com/eslint-visitor-keys)
+[![Build Status](https://github.com/eslint/js/workflows/CI/badge.svg)](https://github.com/eslint/js/actions)
+
+Constants and utilities about visitor keys to traverse AST.
+
+## 💿 Installation
+
+Use [npm] to install.
+
+```bash
+$ npm install eslint-visitor-keys
+```
+
+### Requirements
+
+- [Node.js] `^18.18.0`, `^20.9.0`, or `>=21.1.0`
+
+## 📖 Usage
+
+To use in an ESM file:
+
+```js
+import * as evk from "eslint-visitor-keys"
+```
+
+To use in a CommonJS file:
+
+```js
+const evk = require("eslint-visitor-keys")
+```
+
+### evk.KEYS
+
+> type: `{ [type: string]: string[] | undefined }`
+
+Visitor keys. This keys are frozen.
+
+This is an object. Keys are the type of [ESTree] nodes. Their values are an array of property names which have child nodes.
+
+For example:
+
+```
+console.log(evk.KEYS.AssignmentExpression) // → ["left", "right"]
+```
+
+### evk.getKeys(node)
+
+> type: `(node: object) => string[]`
+
+Get the visitor keys of a given AST node.
+
+This is similar to `Object.keys(node)` of ES Standard, but some keys are excluded: `parent`, `leadingComments`, `trailingComments`, and names which start with `_`.
+
+This will be used to traverse unknown nodes.
+
+For example:
+
+```js
+const node = {
+    type: "AssignmentExpression",
+    left: { type: "Identifier", name: "foo" },
+    right: { type: "Literal", value: 0 }
+}
+console.log(evk.getKeys(node)) // → ["type", "left", "right"]
+```
+
+### evk.unionWith(additionalKeys)
+
+> type: `(additionalKeys: object) => { [type: string]: string[] | undefined }`
+
+Make the union set with `evk.KEYS` and the given keys.
+
+- The order of keys is, `additionalKeys` is at first, then `evk.KEYS` is concatenated after that.
+- It removes duplicated keys as keeping the first one.
+
+For example:
+
+```js
+console.log(evk.unionWith({
+    MethodDefinition: ["decorators"]
+})) // → { ..., MethodDefinition: ["decorators", "key", "value"], ... }
+```
+

+# Espree
+
+Espree started out as a fork of [Esprima](http://esprima.org) v1.2.2, the last stable published released of Esprima before work on ECMAScript 6 began. Espree is now built on top of [Acorn](https://github.com/ternjs/acorn), which has a modular architecture that allows extension of core functionality. The goal of Espree is to produce output that is similar to Esprima with a similar API so that it can be used in place of Esprima.
+
+## Usage
+
+Install:
+
+```
+npm i espree
+```
+
+To use in an ESM file:
+
+```js
+import * as espree from "espree";
+
+const ast = espree.parse(code);
+```
+
+To use in a Common JS file:
+
+```js
+const espree = require("espree");
+
+const ast = espree.parse(code);
+```
+
+## API
+
+### `parse()`
+
+`parse` parses the given code and returns a abstract syntax tree (AST). It takes two parameters.
+
+- `code` [string]() - the code which needs to be parsed.
+- `options (Optional)` [Object]() - read more about this [here](#options).
+
+```js
+import * as espree from "espree";
+
+const ast = espree.parse(code);
+```
+
+**Example :**
+
+```js
+const ast = espree.parse('let foo = "bar"', { ecmaVersion: 6 });
+console.log(ast);
+```
+
+<details><summary>Output</summary>
+<p>
+
+```
+Node {
+  type: 'Program',
+  start: 0,
+  end: 15,
+  body: [
+    Node {
+      type: 'VariableDeclaration',
+      start: 0,
+      end: 15,
+      declarations: [Array],
+      kind: 'let'
+    }
+  ],
+  sourceType: 'script'
+}
+```
+
+</p>
+</details>
+
+### `tokenize()`
+
+`tokenize` returns the tokens of a given code. It takes two parameters.
+
+- `code` [string]() - the code which needs to be parsed.
+- `options (Optional)` [Object]() - read more about this [here](#options).
+
+Even if `options` is empty or undefined or `options.tokens` is `false`, it assigns it to `true` in order to get the `tokens` array
+
+**Example :**
+
+```js
+import * as espree from "espree";
+
+const tokens = espree.tokenize('let foo = "bar"', { ecmaVersion: 6 });
+console.log(tokens);
+```
+
+<details><summary>Output</summary>
+<p>
+
+```
+Token { type: 'Keyword', value: 'let', start: 0, end: 3 },
+Token { type: 'Identifier', value: 'foo', start: 4, end: 7 },
+Token { type: 'Punctuator', value: '=', start: 8, end: 9 },
+Token { type: 'String', value: '"bar"', start: 10, end: 15 }
+```
+
+</p>
+</details>
+
+### `version`
+
+Returns the current `espree` version
+
+### `VisitorKeys`
+
+Returns all visitor keys for traversing the AST from [eslint-visitor-keys](https://github.com/eslint/js/tree/main/packages/eslint-visitor-keys)
+
+### `latestEcmaVersion`
+
+Returns the latest ECMAScript supported by `espree`
+
+### `supportedEcmaVersions`
+
+Returns an array of all supported ECMAScript versions
+
+## Options
+
+```js
+const options = {
+    // attach range information to each node
+    range: false,
+
+    // attach line/column location information to each node
+    loc: false,
+
+    // create a top-level comments array containing all comments
+    comment: false,
+
+    // create a top-level tokens array containing all tokens
+    tokens: false,
+
+    // Set to 3, 5 (the default), 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 or 17 to specify the version of ECMAScript syntax you want to use.
+    // You can also set to 2015 (same as 6), 2016 (same as 7), 2017 (same as 8), 2018 (same as 9), 2019 (same as 10), 2020 (same as 11), 2021 (same as 12), 2022 (same as 13), 2023 (same as 14), 2024 (same as 15), 2025 (same as 16) or 2026 (same as 17) to use the year-based naming.
+    // You can also set "latest" to use the most recently supported version.
+    ecmaVersion: 3,
+
+    allowReserved: true, // only allowed when ecmaVersion is 3
+
+    // specify which type of script you're parsing ("script", "module", or "commonjs")
+    sourceType: "script",
+
+    // specify additional language features
+    ecmaFeatures: {
+
+        // enable JSX parsing
+        jsx: false,
+
+        // enable return in global scope (set to true automatically when sourceType is "commonjs")
+        globalReturn: false,
+
+        // enable implied strict mode (if ecmaVersion >= 5)
+        impliedStrict: false
+    }
+}
+```
+
+## Esprima Compatibility Going Forward
+
+The primary goal is to produce the exact same AST structure and tokens as Esprima, and that takes precedence over anything else. (The AST structure being the [ESTree](https://github.com/estree/estree) API with JSX extensions.) Separate from that, Espree may deviate from what Esprima outputs in terms of where and how comments are attached, as well as what additional information is available on AST nodes. That is to say, Espree may add more things to the AST nodes than Esprima does but the overall AST structure produced will be the same.
+
+Espree may also deviate from Esprima in the interface it exposes.

+
+## Build Commands
+
+* `npm test` - run all tests
+* `npm run lint` - run all linting
+
+## Differences from Espree 2.x
+
+* The `tokenize()` method does not use `ecmaFeatures`. Any string will be tokenized completely based on ECMAScript 6 semantics.
+* Trailing whitespace no longer is counted as part of a node.
+* `let` and `const` declarations are no longer parsed by default. You must opt-in by using an `ecmaVersion` newer than `5` or setting `sourceType` to `module`.
+* The `esparse` and `esvalidate` binary scripts have been removed.
+* There is no `tolerant` option. We will investigate adding this back in the future.
+
+## Known Incompatibilities
+
+In an effort to help those wanting to transition from other parsers to Espree, the following is a list of noteworthy incompatibilities with other parsers. These are known differences that we do not intend to change.
+
+### Esprima 1.2.2
+
+* Esprima counts trailing whitespace as part of each AST node while Espree does not. In Espree, the end of a node is where the last token occurs.
+* Espree does not parse `let` and `const` declarations by default.
+* Error messages returned for parsing errors are different.
+* There are two addition properties on every node and token: `start` and `end`. These represent the same data as `range` and are used internally by Acorn.
+
+### Esprima 2.x
+
+* Esprima 2.x uses a different comment attachment algorithm that results in some comments being added in different places than Espree. The algorithm Espree uses is the same one used in Esprima 1.2.2.
+
+## Frequently Asked Questions
+
+### Why another parser
+
+[ESLint](http://eslint.org) had been relying on Esprima as its parser from the beginning. While that was fine when the JavaScript language was evolving slowly, the pace of development increased dramatically and Esprima had fallen behind. ESLint, like many other tools reliant on Esprima, has been stuck in using new JavaScript language features until Esprima updates, and that caused our users frustration.
+
+We decided the only way for us to move forward was to create our own parser, bringing us inline with JSHint and JSLint, and allowing us to keep implementing new features as we need them. We chose to fork Esprima instead of starting from scratch in order to move as quickly as possible with a compatible API.
+
+With Espree 2.0.0, we are no longer a fork of Esprima but rather a translation layer between Acorn and Esprima syntax. This allows us to put work back into a community-supported parser (Acorn) that is continuing to grow and evolve while maintaining an Esprima-compatible parser for those utilities still built on Esprima.
+
+### Have you tried working with Esprima?
+
+Yes. Since the start of ESLint, we've regularly filed bugs and feature requests with Esprima and will continue to do so. However, there are some different philosophies around how the projects work that need to be worked through. The initial goal was to have Espree track Esprima and eventually merge the two back together, but we ultimately decided that building on top of Acorn was a better choice due to Acorn's plugin support.
+
+### Why don't you just use Acorn?
+
+Acorn is a great JavaScript parser that produces an AST that is compatible with Esprima. Unfortunately, ESLint relies on more than just the AST to do its job. It relies on Esprima's tokens and comment attachment features to get a complete picture of the source code. We investigated switching to Acorn, but the inconsistencies between Esprima and Acorn created too much work for a project like ESLint.
+
+We are building on top of Acorn, however, so that we can contribute back and help make Acorn even better.
+
+### What ECMAScript features do you support?
+
+Espree supports all ECMAScript 2025 features and partially supports ECMAScript 2026 features.
+
+Because ECMAScript 2026 is still under development, we are implementing features as they are finalized. Currently, Espree supports:
+
+* [Explicit Resource Management](https://github.com/tc39/proposal-explicit-resource-management)
+
+See [finished-proposals.md](https://github.com/tc39/proposals/blob/master/finished-proposals.md) to know what features are finalized.
+
+### How do you determine which experimental features to support?
+
+In general, we do not support experimental JavaScript features. We may make exceptions from time to time depending on the maturity of the features.
