Tool to Unminify / Decompress JavaScript

You cannot truly unminify javascript, as minified javascript replaces variable names with letters, as well as removing code comments - these cannot be "undone" as the original information no longer exists.

It appears that you can at least recreate appropriate spacing, but "real" minified javascript cannot be undone.

Unminify CSS: Simplifying Style Sheets for Web Development โ€” Teletype
July 19, 2023 - Minification is widely used to reduce the file size of CSS files by removing unnecessary characters such as spaces, line breaks, and comments.
