Simply paste your TypeScript code into our online editor and click 'Run Code'. The editor automatically transpiles TypeScript to JavaScript and executes it in your browser. No installation, downloads, or setup required - just write code and see instant results.
Yes! Our editor supports all modern TypeScript features including interfaces, generics, type guards, enums, union types, intersection types, decorators, async/await, and more. It uses the official TypeScript compiler (v5.3.3) to ensure full compatibility.
Currently, the editor runs code client-side in your browser without external dependencies. You can write and test TypeScript logic, algorithms, data structures, and pure TypeScript code. For projects requiring npm packages, consider using the code for local development.
Absolutely! All code execution happens 100% in your browser using client-side JavaScript. Your TypeScript code never leaves your computer or gets sent to any server. We don't store, track, or have access to your code - complete privacy guaranteed.
Our editor uses the TypeScript compiler loaded from CDN to transpile your TypeScript code to JavaScript on-the-fly. The compiled JavaScript is then executed in a safe environment, with console.log outputs captured and displayed in real-time.
You can copy your code using the 'Copy' button or download it as a file using the 'Download' option. The code stays in your browser session, but isn't saved permanently. We recommend saving important code to your local machine.
TypeScript provides static type checking, interfaces, and enhanced IDE support compared to JavaScript. Our TypeScript editor offers type safety, IntelliSense autocomplete for types, and catches type errors before runtime. Use TypeScript for larger projects requiring type safety.
Yes! Our editor is perfect for technical interviews, coding challenges, and whiteboard sessions. Share your screen and write TypeScript code with instant execution. It's commonly used for React/Angular interviews, algorithm practice, and code demonstrations.
