Why React exists
How websites render, React’s key features, and the virtual DOM compared with the real DOM — the idea everything else builds on.
Free learning initiative
A free React JS crash course, from setting up your first app to building with components
React is how a large share of modern websites build their interfaces. Jobaaj Learnings is making this crash course free for every student — how React renders, a proper setup with Vite, JSX, and components and props, with a mini project along the way.
No payment step. Open the first lesson straight away.

What you'll learn
Learn React the way developers actually use it
React makes sense once you see what problem it solves. This course starts with how websites render, sets up a real development environment, and then builds up JSX and components one idea at a time.
A real setup
VS Code, Node.js and npm explained, reading the React docs, then new apps with Create React App and with Vite — and which to choose.
JSX, properly
What JSX is, why it uses className and htmlFor, and handling events like onClick.
Conditional rendering and lists
Show or hide UI with ternaries, render lists with map() and keys, and put it together in a mini project.
Components
Class-based and functional components, and why modern React code is written almost entirely as functions.
Props and composition
Passing and destructuring props, default props, composing components, and what props drilling is — and why it becomes a problem.
Why it's free
We built this to be learned from, not sold.
A lot of people who need a skill like this are exactly the people least able to pay for it — students between semesters, freshers before a first job, anyone rebuilding after a break. So we took the fee off.
01
The whole course, not a preview
Every lesson is open from the start. There's no locked second half and no upgrade waiting three modules in.
02
Free because it should be, not for a window
This isn't a promotional price or a trial. There's no clock on it and no fee arriving later.
03
Built to the same standard as the rest
Nothing was trimmed to make it free. It is the same material, at the same depth, as everything else we teach.
04
Yours to keep
Come back to a lesson next month or next year. Access doesn't expire and nothing gets pulled behind a paywall.

Questions people ask before starting
Yes. Jobaaj Learnings provides it free of cost. There’s no fee to start, no trial period that ends, and no payment step anywhere in the flow.
None. The course starts from the very beginning and builds up from there, so you can begin with no prior experience in the subject.
Yes. Every lesson is recorded, so you can pause, rewind and come back whenever it fits around classes or work. There’s no schedule to keep up with.
Yes, the basics — variables, functions, arrays and objects. If you need them first, the Basics of Web Development crash course covers HTML, CSS and JavaScript fundamentals and is also free.
VS Code and Node.js, both free. The setup module walks through installing them and creating your first app with Vite or Create React App.
No — and it’s worth knowing before you start. This course covers the foundations: rendering, setup, JSX, components and props. State and hooks such as useState and useEffect are not in these lessons.
Explain how React renders and what the virtual DOM does, set up a React project with Vite or Create React App, write JSX with events and conditional rendering, render lists with keys, and build and compose functional components that pass data through props.
