ObfuscateJS compress your Javascript files.
The obfuscator currently removes whitespace and comments.
It renames variable names with a local scope to a shorter version,
and as an advanced option it renames all variables with a certain
prefix to a shorter name.

Usage:
    obfuscatejs Obfuscator {src} {dest} {prefix}
    obfuscatejs WeightWatch {src}
    obfuscatejs BuildUtils {srcRootDir} {destDir} {docDir} {headerFile}
