JS / TS Formatting

JavaScript and TypeScript are the dominant languages of the web, but sloppy coding, inconsistent team habits, or compiling engines can result in highly unreadable source code. Maintaining consistent formatting is critical for catching bugs and ensuring code maintainability.

This tool uses Prettier (the de facto standard code formatter for JS/TS/React) natively in your browser to re-format your code. It handles modern ECMAScript features and JSX/TSX syntax perfectly, enforcing standard indentation, quote styles, and trailing commas without ever sending your code to a remote server.
