How to minify and uglify lambda code and how that helps
UglifyJS is a JavaScript parser, minifier, compressor and beautifier toolkit .
UglifyJS can take multiple input files. It's recommended that you pass the input files first, then pass the options. UglifyJS will parse input files in sequence and apply any compression options. The files are parsed in the same global scope, that is, a reference from a file to some variable/function declared in another file will be matched properly.
