  			 * ## Best practices
  			 *
  			 * Since the position of overwriting tokens (token in `redef` that overwrite tokens in the copied language)
  			 * doesn't matter, they can technically be in any order. However, this can be confusing to others that trying to

  			 *

  			 * 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.
  			 * @param {string} before The key to insert before.
  			 * @param {Grammar} insert An object containing the key-value pairs to be inserted.
  			 * @param {Object<string, any>} [root] The object containing `inside`, i.e. the object that contains the
