About TypeScript Playground
The TypeScript Playground is a free browser editor for writing TypeScript and JavaScript. It shows compiled output and type errors without any installation.
What it does
The Playground runs TypeScript in your browser so you can test ideas and see how the compiler reacts. It shows the compiled JavaScript and declaration output, lists errors and logs, and lets you change compiler options. You can share a link to your code with others, which makes it easy to show a problem or an example.
