Minified JavaScript files, such Angular or jQuery, typically still include file information inside an opening comment block. This might include the name and version number of the software, copyright and licensing details, and maybe a URL leading to the original source code form. For example:
/*
ExampleJS v1.3.16
(c) 2010-2014 Example Foundation. http://example.org
License: MIT
*/
Will WebAssembly support some kind of comment or metadata format, for similar file identification purposes?
