What is Deno
Deno is a secure Typescript runtime built on V8, the Google runtime engine for JavaScript.
It was built with:
- Rust (Deno’s core was written in Rust, Node’s in C++)
- Tokio (the event loop written in Rust)
- TypeScript
- V8 (Google’s JavaScript runtime used in Chrome and Node, among others)
Feature Highlights
- Secure by default. No file, network, or environment access (unless explicitly enabled).
- Supports TypeScript out of the box.
- Ships a single executable (deno).
- 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.
- Scripts can be bundled into a single javascript file.
