In VS Code, use the 'Format Selection' shortcut (Cmd/Ctrl + K, F) to clean up specific blocks of code.
JavaScript is the primary programming language of the web, powering interactive features on almost every modern website. TypeScript is a strongly typed superset of JavaScript that compiles to plain JavaScript, adding safety and better tooling for large-scale applications. Because both languages rely heavily on nested structures like functions and objects, consistent formatting is essential to prevent 'callback hell' and maintain code quality.

TypeScript was created by Microsoft and is maintained by Anders Hejlsberg, the lead architect of C#.
While our online tool is perfect for quick fixes, professional workflows often benefit from automation:
husky and lint-staged to format code automatically before every commit.Q: Does this tool support the latest TypeScript versions? A: Yes, our formatter is updated regularly to support the latest TypeScript syntax and ESNext features.
Q: Will formatting my code change how it runs? A: No, the tool only changes the visual layout (whitespace and indentation) and does not alter the logic of your code.
Q: Is there a limit to how much code I can format? A: There is no strict limit, though extremely large files (several megabytes) may slow down your browser performance.
Q: Can I format React code (JSX/TSX)? A: Absolutely! The formatter fully supports JSX and TSX syntax used in React development.
