Can you explain how source maps work with UglifyJS?

Source maps allow you to map your minified code back to the original source code. This is useful for debugging, as it helps you see the original variable names and line numbers in your browser's developer tools.

What options should I enable for better compression?

For better compression, enable options like compress and mangle. You can also use output options to control the formatting of the output code.

Are there any common pitfalls to avoid?
