If you are a developer, you probably have heard of MERN stack. But what is it?

What is the MERN stack?

Using 4 different technologies for different purposes. Still didn't get it? MERN stack is just using 4 different technologies to make a single application. These technologies are:

1. React: React is basically the front-end part of the app.
2. Node: Node is used as back-end or server-side language.
3. MongoDB: MongoDB is where you can make databases (that's all I know)
4. Express: Express is used with Node

These 4 technologies combined are called the MERN stack
