Deno
![](/development/deno/media/commit/2b75a1155906613df16bad9d1eb84f3dc0ba571b/docs/images/deno3.png)
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 like a dependency inspector (deno info) and a code formatter (deno fmt).
- Set of reviewed standard modules that are guaranteed to work with Deno.

Getting Started
Try running a simple program:
deno run https://deno.land/std/examples/welcome.ts
Or a more complex one:
import { serve } from "https://deno.land/std/http/server.ts";
const s = serve({ port: 8000 });
console.log("http://localhost:8000/");
for await (const req of s) {
req.respond({ body: "Hello World\n" });
}
You can find a more in depth introduction, examples, and environment setup guides in the manual.
More in-depth info can be found in the runtime documentation.
