Introduction to
MERN stack
The MERN stack is a popular combination of technologies used for
building dynamic web applications. It consists of MongoDB, Express.js,
React.js, and Node.js. This stack provides a complete framework for
building modern, full-stack applications.

What is MERN stack?
MongoDB Express.js Node.js
MongoDB is a widely used Express.js is a minimal and Node.js is an open-source, cross-
NoSQL database that provides flexible Node.js web application platform JavaScript framework
high performance, automatic framework that provides a used for server-side
scaling, and native replication for robust set of features for web programming, enabling the
data storage. and mobile applications. development of scalable
network applications.
React.js
Component-Based Virtual DOM
Architecture React.js utilizes a virtual Document
React.js uses a component-based Object Model, which improves
approach, making it easier to maintain performance by efficiently updating
and reuse code components across the user interface without affecting
different parts of an application. the entire page.
Declarative Syntax
React.js uses a declarative syntax that makes it simple to design interactive user
interfaces.
Node.js
