+           * ## Best practices

+           * Since the position of overwriting tokens (token in `redef` that overwrite tokens in the copied language)

+           * understand the language definition because, normally, the order of tokens matters in Prism grammars.
+           *
+           * Therefore, it is encouraged to order overwriting tokens according to the positions of the overwritten tokens.
+           * Furthermore, all non-overwriting tokens should be placed after the overwriting ones.
+           *
+           * @param {string} id The id of the language to extend. This has to be a key in `Prism.languages`.
+           * @param {Grammar} redef The new tokens to append.
+           * @returns {Grammar} The new language created.
+           * @public
+           * @example
+           * Prism.languages['css-with-colors'] = Prism.languages.extend('css', {
+           *     // Prism.languages.css already has a 'comment' token, so this token will overwrite CSS' 'comment' token
+           *     // at its original position
+           *     'comment': { ... },
+           *     // CSS doesn't have a 'color' token, so this token will be appended
+           *     'color': /\b(?:red|green|blue)\b/
+           * });

+          /**
+           * Inserts tokens _before_ another token in a language definition or any other grammar.
+           *
+           * ## Usage
+           *
+           * This helper method makes it easy to modify existing languages. For example, the CSS language definition
+           * not only defines CSS highlighting for CSS documents, but also needs to define highlighting for CSS embedded
+           * in HTML through `<style>` elements. To do this, it needs to modify `Prism.languages.markup` and add the
+           * appropriate tokens. However, `Prism.languages.markup` is a regular JavaScript object literal, so if you do
+           * this:
+           *
+           * ```js
+           * Prism.languages.markup.style = {
+           *     // token
+           * };
+           * ```
+           *
+           * then the `style` token will be added (and processed) at the end. `insertBefore` allows you to insert tokens
+           * before existing tokens. For the CSS example above, you would use it like this:
+           *
+           * ```js
+           * Prism.languages.insertBefore('markup', 'cdata', {
+           *     'style': {
+           *         // token
+           *     }
+           * });
+           * ```
+           *
+           * ## Special cases
+           *
+           * If the grammars of `inside` and `insert` have tokens with the same name, the tokens in `inside`'s grammar
+           * will be ignored.
+           *
+           * This behavior can be used to insert tokens after `before`:
+           *
+           * ```js
+           * Prism.languages.insertBefore('markup', 'comment', {
+           *     'comment': Prism.languages.markup.comment,
+           *     // tokens after 'comment'
+           * });
+           * ```
+           *
+           * ## Limitations
+           *
+           * The main problem `insertBefore` has to solve is iteration order. Since ES2015, the iteration order for object
+           * properties is guaranteed to be the insertion order (except for integer keys) but some browsers behave
+           * differently when keys are deleted and re-inserted. So `insertBefore` can't be implemented by temporarily
+           * deleting properties which is necessary to insert at arbitrary positions.
+           *
+           * To solve this problem, `insertBefore` doesn't actually insert the given tokens into the target object.
+           * Instead, it will create a new object and replace all references to the target object with the new one. This
+           * can be done without temporarily deleting properties, so the iteration order is well-defined.
+           *
+           * However, only references that can be reached from `Prism.languages` or `insert` will be replaced. I.e. if
+           * you hold the target object in a variable, then the value of the variable will not change.
+           *
+           * ```js
+           * var oldMarkup = Prism.languages.markup;
+           * var newMarkup = Prism.languages.insertBefore('markup', 'comment', { ... });
+           *
+           * assert(oldMarkup !== Prism.languages.markup);
+           * assert(newMarkup === Prism.languages.markup);
+           * ```
+           *
+           * @param {string} inside The property of `root` (e.g. a language id in `Prism.languages`) that contains the
+           * object to be modified.
