It's not uncommon, when scripting for Adobe applications, to borrow JS libraries that have been originally written for web development. While the new generation of Adobe HTML Extensions will run on the Chromium Embedded Framework, traditional ExtendScript code is based upon a different, older engine. Besides ECMAScript unsupported features (i.e. ES 5) I've noticed that using minified JS code is a risky business - scripts can break or fail silently. I've set up a proper testing environment to inspect them.
