A modern runtime for JavaScript and TypeScript.

This commit marks the `Deno.iter` and `Deno.iterSync` utils as deprecated, and schedules them for removal in Deno 2.0. These utilities are implemented in pure JS, so should not be part of the Deno namespace. These utilities are now available in std/io/util: denoland/deno_std#843. |

Deno
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.
