Mern Stack – What Is It? Introduction & Benefits

The MERN stack is a popular technology stack used for developing web applications. It consists of four technologies: MongoDB, Express.js, React.js, and Node.js. MongoDB is a NoSQL database used to store data, Express.js is a server-side web application framework, React.js is a client-side user interface framework, and Node.js is a server-side JavaScript runtime environment.

The MERN stack is popular because it allows developers to build full-stack web applications using only one programming language – JavaScript. This reduces development time and makes it easier for developers to switch between front-end and back-end development. Additionally, the MERN stack is highly scalable, flexible, and offers good performance.
