What is Deno?

Deno is a secure JavaScript and TypeScript runtime built on V8 and Rust, created by Ryan Dahl (the original creator of Node.js). It runs TypeScript natively without a compilation step, has secure-by-default sandboxing, and implements modern web standard APIs. Deno 2 brings full Node.js and npm compatibility.

            🚀 Why Latest Versions Matter: Deno is actively developed with major improvements in each release, including enhanced Node.js/npm compatibility, performance improvements, and new web platform API implementations. Latest versions include critical security patches and improved TypeScript support.

Lightweight Deno runtime without the developer tooling. Ideal for production deployments where you only need to run compiled Deno programs with minimal overhead and a smaller binary footprint.

sudo apt install denort

🔄 Managing Both Packages

You can install both deno and denort simultaneously:

Install both:

sudo apt install deno denort

Check deno version:

deno --version
