About this app

React organizes user interfaces into reusable components that respond to state changes in a declarative way. This app covers everything from JSX and props to advanced hooks and external API integration.

The focus is on the correct React mental model: understanding why state works the way it does prevents most common beginner mistakes.

What you’ll study

• JSX and rendering
• Components and props
• State with useState
• Effects with useEffect
• Custom hooks
• API consumption and Context API

How it works

Content is organized in modules. You’ll find exercises with feedback, an in-app IDE to try code snippets, saved progress, and a completion certificate, plus a premium option without ads.

Who it’s for

• JavaScript developers who want to learn the leading front-end library
• Modern web development students
• Professionals migrating from other UI frameworks

Start with the first module and move forward as your schedule allows.
