You can do this on minified code with beautifiers like js-beautify, for example. It's not clear why we need to make this an LLM task when we have existing simple scripts to do it?
While this doesn't restore minified identifiers, like the LLM version claims to do, it tends to help a lot with understanding the code. Usually minified code still has the original identifiers in global function names, object attributes, DOM classes and a few other places where it is hard to guarantee no side effects of name mangling. This makes guessing the purpose of the remaining identifiers substantially easier to a human, and it is probably also the main reason why an LLM is capable of making reasonable guesses at what they could reasonably be called.
