How to use TypeScript Online Compiler

  1. Type or paste your TypeScript in the editor.

  3. The code is compiled to JavaScript and run; output appears in the Output panel.
  4. Use Format to tidy the code, or Reset to start over.

A quick TypeScript scratchpad

This compiler lets you try TypeScript and see it run. It transpiles your code to JavaScript in the browser using Sucrase, then executes it, showing console output on the right. It is fast because it removes the types rather than running a full type-checker, which is exactly what you want for trying ideas and exercises.

Tips

Use console.log() to print values. If you want full type-checking and errors as you type, the official TypeScript Playground or a local editor is the better tool; this page is for quick runs and output.
