		* Removes both single and multi-line comments
		* Removes unnecessary gaps left by comment blocks
		* Does not change the resulting layout / formatting
		* Can handle valid JSON or JavaScript of any size
		* Removes both single and multi-line comments from JSON, JavaScript and CSS
		* Automatically recognizes HTML and removes all `<!-- comments -->` from it
		* Removes unnecessary gaps on empty lines and the ones left by comment blocks
		* Does not change layout / formatting of the original document
		* Can handle input code of any size
		* Compliant with ECMAScript 6

		The library does not support mixed content - HTML with JavaScript or CSS in it.
		Once the input code is recognized as HTML, only the HTML comments will be removed from it.

		### Performance

		In terms of the performance, this library is as fast as it gets, in part because it makes no use of regular expressions.

		For example, it churns through [AngularJS 1.5 Core](https://code.angularjs.org/1.5.0-rc.0/angular.js) (1.1MB ~ 30,000 lines of JavaScript) in under 40ms.
