Is mern stack full stack
The MERN stack is a full-stack web development technology that can build both front-end and back-end web applications. The MERN stack comprises four open-source technologies: MongoDB, Express, React, and Node.js, which provide a comprehensive solution for building full-stack web applications.
MongoDB is a NoSQL database that allows developers to store and manage data efficiently. At the same time, Express is a lightweight framework that gives a set of features for building server-side applications. React is a JavaScript store used to generate user interfaces, whereas Node.js is a server-side runtime program that enables creators to run JavaScript.
These technologies make developers build full-stack web applications using a single programming language, JavaScript. That makes it easier for developers to create scalable and efficient web applications that handle large amounts of data and traffic.
The MERN stack is used to build web applications such as e-commerce, social media platforms, websites, and content management systems. It also builds real-time web applications such as chat and collaboration tools.
