What is the difference between minify and uglify?

#Uglification is the act of transforming the code into an "unreadable" form, that is, renaming variables/functions to hide the original intent It is, also, irreversable. #Minifying is just removing unnecessary white-space and redundant like comments and semicolons. And it can be reversed back when needed.

Does Minifying JavaScript improve performance?

Minifying strips out all comments, superfluous white space and shortens variable names. It thus reduces download time for your JavaScript files as they are (usually) a lot smaller in filesize. So, yes it does improve performance. The obfuscation shouldn't adversely affect performance.

What is UglifyJS?

UglifyJS is a JavaScript compressor/minifier written in JavaScript. It also contains tools that allow one to automate working with JavaScript code: A parser which produces an abstract syntax tree (AST) from JavaScript code. A compressor (optimizer) — it uses the transformer API to optimize an AST into a smaller one.
