About TypeScript Formatting
What is TypeScript?
TypeScript is a strongly-typed superset of JavaScript that adds static type annotations, interfaces, generics, and enums. It compiles to plain JavaScript and catches type errors at build time, making large codebases safer and easier to maintain.
How to Format TypeScript Online
Paste your TypeScript code, click Format, and get beautifully indented code. The tool understands TypeScript-specific syntax including interfaces, type annotations, generics, enums, and decorators. It validates using a real TypeScript-aware parser.
TypeScript vs JavaScript Formatting
TypeScript formatting follows the same rules as JavaScript (indentation, brace style, line wrapping) but also handles type annotations, interface declarations, generic type parameters, and enum definitions. Our formatter handles both seamlessly.
