What do tech giants, like Netflix and PayPal, have in common? Yes, it is JavaScript.

The reasons why big companies use React.js and Node.js

In today’s highly competitive technical environment, businesses are seeking ways to engage customers on the devices they mainly use to gain an edge over the competition. Depending on the application’s needs, many developers prefer using JavaScript runtime environments, such as Node.js in conjunction with React.js, to create the high-performing applications that businesses need.

Node.js is an open-source, cross-platform runtime environment. It is a JS runtime platform powered by Google Chrome V8 JavaScript Engine. Node.js can be described as JavaScript that can run on the computer, instead of the browser, like normal JS. This has been made possible by the V8 JavaScript runtime engine.

Based on a modular architecture, Node.js simplifies the development of complex applications. It works on an event-driven, non-blocking I/O model and is adapted for developing server-side applications in JavaScript. It allows you to build utilities that you can concatenate and create JavaScript files with, and do this on your machine.
