Overall, MERN is one of the most popular tech stacks in use today and is highly demanded within the IT industry.

Introduction to MERN Stack00:00:04

MERN stands for MongoDB, Express, React, and Node.js. It is a popular JavaScript-based tech stack used to build full-stack web applications, which include both a front-end (user interface) and a back-end (server logic and data).

Front-End with React00:00:35

React, along with JavaScript, HTML, and CSS, is used to build the front-end of MERN applications. ReactJS is a JavaScript library specifically designed for building user interfaces.

Back-End Components: Node, Express, and MongoDB00:00:50

Node.js, Express.js, and MongoDB are used to build the back-end. Node.js is a JavaScript runtime environment for server-side scripting. MongoDB is a NoSQL database for data storage and management. Express.js is a web application framework for Node.js, used to build server-side applications and APIs.
