Node.js is Dead – Long live Deno

Deno is a new runtime for JavaScript and TypeScript, invented by Ryan Dahl - the original author/creator of Node.js. The persistence of this project to fix design problems in Node.js described in Dahl's famous talk "10 Things I Regret About Node.js". Here I am providing depth differences between Node.js and Deno.

Differences between Node.js and Deno

Deno	Node.Js
Deno does not use npm It uses modules referenced as URLs or file paths	Use npm
Deno does not use package.json	Node use package.json for dependency and module management
All async actions in Deno return a promise	The async_hooks module provides an API to track asynchronous resources.
Deno requires explicit permissions for the file, network, and environment access	Node.js does not required any explicit permissions to access network files. It has all default permissions.
Deno always dies on uncaught errors	Node.js follows a callback pattern where an error object is the first argument and data is the second argument.
Uses "ES Modules" and does not support require()Uses "ES Modules" and does not support require() import * as the log from "https://deno.land/std/log/mod.ts"	Node.js use required() method to import libraries
Modules/files loaded from remote URLs are intended to be immutable and cacheable	All the module(npm-modules) reside under your work repository
