What is deno?
Deno is a runtime for JavaScript and TypeScript that is based on the V8 JavaScript engine and the Rust programming language. It was created by Ryan Dahl, original creator of Node.js, and is focused on productivity. It was announced by Dahl in 2018 during his talk "10 Things I Regret About Node.js".
advantages of deno
- fast and safe
- typescript support
- new dependency management system
- best adaptation of ecmascript
Why use deno?
Over time, technologies evolve and improve, this is the case of nodejs and one of the most common improvements is that we will avoid the tedious node_modulos folder and it will no longer be necessary to have 1gib of modules since it does not handle the modules in the cache. better way.
