| // This file aims to provide a quick, fast, small-as-possible-while-avoiding-encoding-errors solution for those who | |
| // are interested in parsing javascirpt files using javascript. What this does do is it determines whether a string | |
| // is a valid javascript variable name according to the variable name's code points. What this script does not do is | |
| // determine whether or not that variable is already a reserved keyword. If you need that check, then look elsewhere. | |
| // NOTE: This is the unminified file-part. To use this file, place this file INSIDE the global IIFE around your code | |
| // before any calls to it. But, don't distribute it just yet. The source code is rather large. Instead, you must | |
| // minify it before you incorperate it into the end product website using the closure compiler. Online access to the | |
| // Closure Compiler can be found at https://closure-compiler.appspot.com. |
