What is MERN Stack?
MERN stack is a powerful and popular technology stack used for full-stack web development. It comprises four main technologies: MongoDB, Express.js, React, and Node.js.
1. MongoDB
MongoDB is a NoSQL database that allows for flexible and scalable data storage, using a document-oriented approach. It stores data in JSON-like format, making it easy for developers to work with JavaScript objects.
2. Express.js
Express.js is a web application framework for Node.js, designed to build web applications and APIs. It simplifies the development process by providing robust features for building server-side logic and handling HTTP requests.
3. React
React is a JavaScript library for building user interfaces, primarily for single-page applications. It enables developers to create reusable UI components and manage the application state efficiently, leading to a smooth user experience.
4. Node.js
Node.js is a runtime environment that allows developers to execute JavaScript on the server side. It is built on the V8 JavaScript engine and is known for its event-driven architecture and non-blocking I/O, which enhance application performance.
In summary, the MERN stack provides a cohesive set of technologies that enable developers to create dynamic web applications with a seamless integration between client-side and server-side components.
