318
			 *
319
			 * ## Best practices
320
			 *
321
			 * Since the position of overwriting tokens (token in `redef` that overwrite tokens in the copied language)
322
			 * doesn't matter, they can technically be in any order. However, this can be confusing to others that trying to
323
			 * understand the language definition because, normally, the order of tokens matters in Prism grammars.
324
			 *
325
			 * Therefore, it is encouraged to order overwriting tokens according to the positions of the overwritten tokens.
326
			 * Furthermore, all non-overwriting tokens should be placed after the overwriting ones.
327
			 *
328
			 * @param {string} id The id of the language to extend. This has to be a key in `Prism.languages`.
329
			 * @param {Grammar} redef The new tokens to append.
330
			 * @returns {Grammar} The new language created.
331
			 * @public
332
			 * @example
333
			 * Prism.languages['css-with-colors'] = Prism.languages.extend('css', {
334
			 *     // Prism.languages.css already has a 'comment' token, so this token will overwrite CSS' 'comment' token
335
			 *     // at its original position
336
			 *     'comment': { ... },
337
			 *     // CSS doesn't have a 'color' token, so this token will be appended
338
			 *     'color': /\b(?:red|green|blue)\b/
339
			 * });

351
			/**
352
			 * Inserts tokens _before_ another token in a language definition or any other grammar.
353
			 *
354
			 * ## Usage
355
			 *
356
			 * This helper method makes it easy to modify existing languages. For example, the CSS language definition
357
			 * not only defines CSS highlighting for CSS documents, but also needs to define highlighting for CSS embedded
358
			 * in HTML through `<style>` elements. To do this, it needs to modify `Prism.languages.markup` and add the
359
			 * appropriate tokens. However, `Prism.languages.markup` is a regular JavaScript object literal, so if you do
360
			 * this:
361
			 *
362
			 * ```js
363
			 * Prism.languages.markup.style = {
364
			 *     // token
365
			 * };
366
			 * ```
367
			 *
368
			 * then the `style` token will be added (and processed) at the end. `insertBefore` allows you to insert tokens
369
			 * before existing tokens. For the CSS example above, you would use it like this:
370
			 *
371
			 * ```js
372
			 * Prism.languages.insertBefore('markup', 'cdata', {
373
			 *     'style': {
374
			 *         // token
375
			 *     }
376
			 * });
377
			 * ```
378
			 *
379
			 * ## Special cases
380
			 *
381
			 * If the grammars of `inside` and `insert` have tokens with the same name, the tokens in `inside`'s grammar
382
			 * will be ignored.
383
			 *
384
			 * This behavior can be used to insert tokens after `before`:
385
			 *
386
			 * ```js
387
			 * Prism.languages.insertBefore('markup', 'comment', {
388
			 *     'comment': Prism.languages.markup.comment,
389
			 *     // tokens after 'comment'
390
			 * });
391
			 * ```
392
			 *
393
			 * ## Limitations
394
			 *
395
			 * The main problem `insertBefore` has to solve is iteration order. Since ES2015, the iteration order for object
396
			 * properties is guaranteed to be the insertion order (except for integer keys) but some browsers behave
397
			 * differently when keys are deleted and re-inserted. So `insertBefore` can't be implemented by temporarily
398
			 * deleting properties which is necessary to insert at arbitrary positions.
399
			 *
400
			 * To solve this problem, `insertBefore` doesn't actually insert the given tokens into the target object.
401
			 * Instead, it will create a new object and replace all references to the target object with the new one. This
402
			 * can be done without temporarily deleting properties, so the iteration order is well-defined.
403
			 *
404
			 * However, only references that can be reached from `Prism.languages` or `insert` will be replaced. I.e. if
405
			 * you hold the target object in a variable, then the value of the variable will not change.
406
			 *
407
			 * ```js
408
			 * var oldMarkup = Prism.languages.markup;
409
			 * var newMarkup = Prism.languages.insertBefore('markup', 'comment', { ... });
410
			 *
411
			 * assert(oldMarkup !== Prism.languages.markup);
412
			 * assert(newMarkup === Prism.languages.markup);
413
			 * ```
414
			 *
415
			 * @param {string} inside The property of `root` (e.g. a language id in `Prism.languages`) that contains the
416
			 * object to be modified.
