Real TypeScript compiler in the browser — see compiled JS, type errors, and AST live.
(compile output will appear here)
Real typescript compiler. Compiles + type-checks live as you type. JSX toggle switches to .tsx input. Note: full lib.dom.d.ts / lib.es*.d.ts isn't loaded — most type errors still surface but DOM and built-in types may show as unknown.
Write TypeScript in your browser, see compiled JavaScript and type-check errors live. Pick the target (ES2015 → ESNext), toggle strict mode, enable JSX, choose module format. Output panel switches between compiled JS, type errors, and AST. Everything runs locally with the real TypeScript compiler.
