Deno

Deno is a runtime environment for JavaScript, TypeScript, and WebAssembly.

Like Node.js, Deno is based on the V8 JavaScript engine and enables developers to run JavaScript outside browsers. However, there are some notable differences between Node and Deno. In particular, Deno:

  • Has built-in support for TypeScript.
  • Restricts file system and network access by default.
  • Includes a large standard library, including implementations of many Web APIs.
  • Does not depend on a centralized registry, instead allowing modules to be loaded from URLs.
