Deno is a runtime for JavaScript and TypeScript that is based on the V8 JavaScript engine and the Rust programming language.
Created by Ryan Dahl, creator of Node.js, Deno is focused on security and productivity. It was announced by Dahl in 2018 during his talk "10 Things I Regret About Node.js". Deno explicitly takes on the role of both runtime and package manager within a single executable, rather than requiring a separate package-management program.
Deno is written in Rust, while Node.js is written in C++.
