Deno is a simple, modern and secure runtime for JavaScript and TypeScript that uses V8 and is built in Rust. * Secure by default. No file, network, or environment access, unless explicitly enabled. * Supports TypeScript out of the box. * Ships only a single executable file. * Has built-in utilities like a dependency inspector (deno info) and a code formatter (deno fmt). * Has a set of reviewed (audited) standard modules that are guaranteed to work with Deno: [deno.land/std](https://deno.land/std)
