Что такое JS2TS?
JS2TS is an online converter for JavaScript-to-TypeScript migration. It uses AI to turn pasted JavaScript into typed TypeScript by adding annotations, interfaces, generics, and other type constructs that fit the input code.
The site positions the tool as a quick way to reduce manual migration work: instead of renaming files and adding types by hand, users paste code, convert it, and copy the TypeScript output. The same site also offers adjacent tools for TypeScript to JavaScript, TypeScript to Zod, and JSON to TypeScript conversions.
Что умеет JS2TS?
Broad TypeScript syntax coverage
Supports common migration patterns including function parameters and return values, object shapes, arrays, unions, intersections, classes, async code, and module syntax.
Fast browser-based workflow
Provides a simple paste-and-convert workflow with instant output in the browser.
Reverse conversion tool
Offers a separate TypeScript to JavaScript converter for stripping TypeScript-specific syntax back to plain JavaScript.

No-login, real-time processing
States that conversions are processed in real time and not stored on the server.
Варианты использования
“Migrate JS projects to TypeScript”
Convert existing JavaScript files into typed TypeScript when you want faster migration than doing the annotations by hand.
“Work with React and Node.js code”
Transform React components and Node.js modules into typed output that better fits larger application codebases.
“Convert TypeScript to JavaScript”
Strip TypeScript syntax back to plain JavaScript when you need code that can run without a TypeScript compiler.
“Derive validation schemas from types”
Generate Zod schemas from TypeScript interfaces when you need runtime validation in addition to compile-time types.
“Create TypeScript interfaces from JSON”
Turn JSON into TypeScript interfaces when starting from API responses or structured data payloads.
