JavaScript Formatter

Format and beautify JavaScript code using a lightweight native bracket parser.

Note: This is a lightweight bracket-matching formatter to quickly prettify minified blocks. It is not a full AST parser (like Prettier) and may struggle with complex ES6 string templates or inline functions.
