Introducing Deno and its history

Deno introduction#

Welcome to your first lesson about Deno. In short, Deno is a JavaScript and TypeScript runtime that adheres to theWeb APIs.

History of Deno#

Ryan Dahl is the creator of Node and released version 1.0 of Deno on May 13th, 2020 as a solution to the issues he discusses in10 Things I Regret About Node.js.

If you have experience in any kind of JavaScript development, you will certainly have used Node and Node Package Manager (npm) at one point, for better or for worse. Due to certain design decisions, and backward compatibility, Node is not fully aligned with the Web APIs, and this can prove problematic when wanting to support both server and browser during development. Deno was therefore created to provide a fresh start for the JavaScript development environment, and even includes native TypeScript support.
