About this app

Learn React by building, not just watching. Interactive lessons take you from your very first component to complete, working web apps — with an AI mentor answering your questions at every step.
React is the most in-demand frontend skill in the world, and this app turns it into bite-size lessons you can actually finish: read a concept, write real code, get instant feedback, move on.
No video marathons. No setup. Just you, a code editor and steady progress.

WHAT YOU'LL BE ABLE TO DO
• Build modern web apps with components, props and state
• Master React hooks — useState, useEffect and your own custom hooks
• Write clean JSX and handle events, forms and lists with confidence
• Manage app-wide state and share data between components
• Fetch data from APIs and render dynamic, real-world content
• Structure projects the way professional React developers do
