       *
       * ## 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
       * 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/
       * });
       */

        return lang;
      },

      /**
       * 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
