Most scripts do not need a bundler, they need their whitespace back. I shipped a 60 kilobyte snippet to a client page that was 20 kilobytes of comments and indentation. The minifier made the file honest.
It strips comments and whitespace and shortens local names with a lightweight tokenizer. It is conservative by design, so test the output still runs, and keep the original readable version for the next dev who inherits the file.

Bottom line: minify at the edge before you reach for a whole build tool.
