What is MERN full-stack?

"In technical terms, the MERN stack combines technologies used to develop web applications. It includes MongoDB, Express.js, React.js, and Node.js. These technologies work together to enable the creation of dynamic and interactive web applications.

A MERN stack developer uses these technologies to build the front-end and back-end of web applications. They leverage the power of MongoDB to store and manage data, Express.js for server-side logic, React.js for building user interfaces, and Node.js as the server-side runtime environment.

By mastering the MERN stack, developers can create efficient and scalable web applications. The demand for MERN stack developers is expected to grow, making it a promising career choice for those interested in web development."

6 Reasons Why You Should Become A MERN Developer?
