deep-is
==========
Node's `assert.deepEqual() algorithm` as a standalone module. Exactly like
[deep-equal](path_to_url except for the fact that `deepEqual(NaN, NaN) === true`.
This module is around [5 times faster](path_to_url
than wrapping `assert.deepEqual()` in a `try/catch`.
[;
console.dir([
equal(
{ a : [ 2, 3 ], b : [ 4 ] },
{ a : [ 2, 3 ], b : [ 4 ] }
),

{ x : 5, y : 6 }
)
]);
```
methods
=======
var deepIs = require('deep-is')
deepIs(a, b)
---------------
Compare objects `a` and `b`, returning whether they are equal according to a
recursive equality algorithm.
install
=======
With [npm](path_to_url do:
```
npm install deep-is
```
test
====
With [npm](path_to_url do:
```
npm test
```
license
=======

<p><strong>Esprima</strong> is a high performance, standard-compliant
<a href="path_to_url">ECMAScript</a> parser written in ECMAScript (also popularly known as
<a href="path_to_url">JavaScript</a>).</p>
<div class="row">
<div class="twelve columns">
<h4>Features</h4>
<ul class="square">
<li>Full support for ECMAScript 5.1 (<a href="path_to_url">ECMA-262</a>)</li>
<li>Sensible <a href="doc/index.html#ast">syntax tree format</a>, compatible with Mozilla <a href="path_to_url">Parser AST</a></li>
<li>Optional tracking of syntax node location (index-based and line-column)</li>
<li>Heavily tested (> 600 <a href="path_to_url">tests</a> with solid statement and branch coverage)</li>
<li>Experimental support for ES6/Harmony (module, class, destructuring, ...)</li>
</ul>
<p></p>
<p>Esprima serves as an important <strong>building block</strong> for some JavaScript language tools,
from <a href="demo/functiontrace.html">code instrumentation</a> to <a href="demo/autocomplete.html">editor autocompletion</a>.</p>
<a href="demo/autocomplete.html"><img src="assets/images/autocomplete.png" width="562" height="295" alt="Autocomplete"></a></p>
</div>
</div>
</div>
<div class="four columns">
<div class="panel">
<p>Once the full syntax tree is obtained, various <strong>static code analysis</strong>
can be applied to give an insight to the code:
<a href="demo/parse.html">syntax visualization</a>,
<a href="demo/validate.html">code validation</a>,
<a href="demo/autocomplete.html">editing autocomplete</a> (with type inferencing)
and <a href="demo/index.html">many others</a>.</p>
</div>
<div class="panel">
<p>Regenerating the code from the syntax tree permits a few different types of <strong>code transformation</strong>,
from a simple <a href="demo/rewrite.html">rewriting</a> (with specific formatting) to
a more complicated <a href="demo/minify.html">minification</a>.</p>
</div>
<p>Esprima runs on many popular web browsers, as well as other ECMAScript platforms such as
<a href="path_to_url">Rhino</a> and
<a href="path_to_url">Node.js</a>. It is distributed under the
<a href="path_to_url">BSD license</a>.</p>

// Some notable changes:
// * Removed unsupported features (destructuring, let, comprehensions...).
// * Removed tests for E4X (ECMAScript for XML).
// * Removed everything related to builder.
// * Enclosed every 'Pattern' construct with a scope.
// * Removed the test for bug 632030 and bug 632024.
