What Is Node.js Used For?

Node.js is an open-source Javascript runtime environment and library for executing and running web applications outside a client's browser. It's based on V8, an engine developed by the Chromium Project for web browsers like Google Chrome and Edge.

Consider a scenario where a user interacts with a web application: he only interacts with the application's front-end, but there's a lot of work that goes behind the scenes.

Now, you know that there's a front-end, a server, and a database in a web application. The front-end is developed using Javascript and frameworks like Angular and React JS, while the server is built on Java, PHP, or Node.js, and the back-end database that stores the data usually consists of MySQL or MongoDB.

Let’s take a closer look at what Node.js is, what it is used for, and how it can be a possible solution for your web development project.
