RuntimeN

Node.js

Runs JavaScript on the server.

One language, four tools. A click in React calls an Express route on Node, which reads or writes MongoDB and sends JSON back.

01 · The basics

What is the MERN stack?

It is a set of four JavaScript tools that together cover every layer of a web app. Here is how one user action moves through them.

User clicks in React

The interface reacts and prepares a request.

Request reaches Express

A route on your API receives and checks it.

Node runs your logic

Server code applies rules, login and validation.

MongoDB saves or finds data

Documents are stored or read from collections.

JSON returns to React

The screen updates with fresh data.

07 · FAQ

Questions people ask

Do I need coding experience?

No. The course starts with JavaScript basics and builds up step by step.

What is the difference between MERN and MEAN?

MEAN uses Angular for the front end, while MERN uses React. The rest of the stack is the same.

Why MongoDB instead of an SQL database?

MongoDB stores flexible documents, while SQL databases use tables. Both are useful, and the course explains when to choose each.

Will I build projects?

Yes. You build and deploy apps you can show in your portfolio.

Do I need data structures and algorithms too?

They help in technical interviews. Many learners pair this course with a separate DSA course.
