What is the MERN stack and why is it popular?

This question asks about the components of the MERN stack (MongoDB, Express, React, Node) and the reasons it’s widely adopted in web development.

The MERN stack is a full-stack JavaScript solution consisting of MongoDB, Express.js, React.js, and Node.js ([turn0search0]turn0search6]). It enables end-to-end development using a unified language (JavaScript). • MongoDB stores flexible, JSON-like documents. • Express.js simplifies server-side routing and middleware. • React.js manages dynamic UI components with a virtual DOM for efficient updates. • Node.js handles backend logic via a non-blocking, event-driven runtime. Why it’s popular: • Enables fast, scalable single-page applications (SPAs) and real-time apps. • Uses JSON consistently from client to server to database. • Enables rapid development and full-stack efficiency. • Widely used by companies and open-source communities ([turn0search48]turn0search12]).
