The rise of JavaScript and Node.js
JavaScript, being a dynamic language, is processed by all browsers asynchronously and provides a seamless UI/UX experience for users. JavaScript has become the de facto language for building client-side applications as it supports almost all web standards and protocols.
Since the introduction of runtime Node.js in 2009 by Ryan Dahl, JavaScript has become one of the most favored choices for building large-scale backend applications. Applications that are data intensive, real time, and have high input/output operations are ideal use cases for JavaScript with the Node.js environment. Let's understand Node.js in more depth.
Node.js
Node.js is a JavaScript runtime built on Google's V8 JavaScript engine. It is open source and built to run on all platforms. It provides an event-driven, non-blocking input/output model which makes it very light, fast, and efficient. Applications built using Node.js are scalable and have very high throughput.
