Deno vs Node | Is Node.js Dead?

Deno vs Node is a very hot topic for the discussion in developer and programmers community since Deno version 1.0 got released.

Node.js and Deno both is very similar. But the question is if we already have Node.js then what is the need for Deno. So Answers of this question is Since JavaScript has changed a lot since 2009 (when node.js was created). Now we have support for Promises, Async/Await, ES modules, Typed Arrays, and TypeScript, etc. Deno has built-in support of these new JavaScript features.

We will discuss the key differences and similarities between Deno and Node.js

Let's understand both using following key points.
1. ES6 Support:

Deno uses ES Modules as the default module system, whereas Node.js uses CommonJS.

2. TypeScript Support:

Deno supports TypeScript out of the box, which means that we don’t need to manually install and configure tools to write TypeScript code.

3. Package Manager (NPM):

In Deno, External dependencies are loaded using URLs, similar to browsers. There is also no package manager and centralized registry like NPM - node_modules.

In short - Deno doesn't use NPM like Node.js. Deno uses modules referenced as URLs.

Deno does not use package.json.

4. Security:

In Node.js application by default has permission to system calls, environment variables, accessing files, sockets, network etc.

In Deno application you have to provide permissions to the code for system calls, environment variables, accessing files, sockets, network etc.

5. Built-in Tools:

Deno also provides a set of built-in tools, like a test runner, code formatter and bundler, etc.

Is NodeJS Dead?
