How to install latest Node.js on Linux

Node.JS is a JavaScript runtime built on Chrome’s V8 JavaScript engine. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient. Node.js’ package ecosystem, npm, is the largest ecosystem of open source libraries in the world.

Node.JS Key Features

  • Asynchronous and Event Driven − All APIs of the library are asynchronous, that is, non-blocking. It essentially means a NodeJS based server never waits for an API to return data. The server moves to the next API after calling it and a notification mechanism of Events of NodeJS helps the server to get a response from the previous API call.
  • Very Fast − Being built on Google Chrome’s V8 JavaScript Engine, NodeJS library is very fast in code execution.
  • Single Threaded but Highly Scalable − NodeJS uses a single threaded model with event looping. Event mechanism helps the server to respond in a non-blocking way and makes the server highly scalable as opposed to traditional servers which create limited threads to handle requests. Node.js uses a single threaded program and the same program can provide service to a much larger number of requests than traditional servers like Apache HTTP Server.
  • No Buffering − Node.js applications never buffer any data. These applications simply output the data in chunks.
  • License − Node.js is released under the MIT license
