* Creates a deep copy of the language with the given id and appends the given tokens.
*
* If a token in `redef` also appears in the copied language, then the existing token in the copied language
* will be overwritten at its original position.
*
* ## 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/
* });

/**
* 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
* object to be modified.
*
* Defaults to `Prism.languages`.

* 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': { ... },

* ## 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
* object to be modified.
*
* Defaults to `Prism.languages`.
* @returns {Grammar} The new grammar object.
