What is MERN stack?

The MERN stack is a collection of technologies that comprise a full-stack capable of building applications with JavaScript. Because JavaScript is a front-end programming language, developers need additional tools in order to ensure functionality on the back end. MongoDB, Express, React, and Node.js are among the tools used by developers today. These tools make up the MERN stack.

MongoDB provides developers with a database they can connect to, while Express builds the back-end framework. The React library allows them to add interactive elements to their applications, and Node.js enables applications to run outside a user’s browser.

By using these technologies together with JavaScript, developers can rapidly build robust web applications with minimal effort. It is used for everything from social media sites to complex enterprise solutions.
