Deno is a _simple_, _modern_ and _secure_ runtime for **JavaScript** and
**TypeScript** that uses V8 and is built in Rust.
### Features
- Secure by default. No file, network, or environment access, unless explicitly
enabled.
- Supports TypeScript out of the box.
- Ships only a single executable file.
- [Built-in utilities.](https://deno.land/manual/tools#built-in-tooling)
- Set of reviewed standard modules that are guaranteed to work with
[Deno](https://deno.land/std/).

### Getting Started
Try running a simple program:
```sh
deno run https://deno.land/std/examples/welcome.ts
```
Or a more complex one:
```ts
const listener = Deno.listen({ port: 8000 });
console.log("http://localhost:8000/");
for await (const conn of listener) {
serve(conn);
}
async function serve(conn: Deno.Conn) {
for await (const { respondWith } of Deno.serveHttp(conn)) {
respondWith(new Response("Hello world"));
}
}
```
You can find a deeper introduction, examples, and environment setup guides in
the [manual](https://deno.land/manual).
The complete API reference is available at the runtime
[documentation](https://doc.deno.land).
