Detailed Description

JSMinPlus version 1.4.

Minifies a javascript file using a javascript parser

This implements a PHP port of Brendan Eich's Narcissus open source javascript engine (in javascript) References: https://en.wikipedia.org/wiki/Narcissus_(JavaScript_engine) Narcissus sourcecode: https://mxr.mozilla.org/mozilla/source/js/narcissus/ JSMinPlus weblog: https://crisp.tweakblogs.net/blog/cat/716
