Build real components in a live preview, graded on what they actually render. Short exercises, real projects, and an AI tutor that reads your code.
React took over frontend development by asking one question: what if your UI was just a function of your data? Instead of manually poking at the page, you describe what the interface should look like for a given state - and React keeps reality in sync.
That idea - components, props, state - is now the shared grammar of modern frontend work, whatever framework a team happens to use. Learn it properly once and every UI codebase starts to look familiar.
In deliberately small pieces. React tutorials love to build one enormous app over hours of video; the trouble is you leave having watched React, not written it. Devpuff gives you focused exercises - build this component, lift this state, fix this stale render - with automated checks on each and Puff on call when a hook behaves mysteriously.
React Intermediate consolidates components, props, state, and effects into working muscle memory. React Advanced pushes into the patterns real codebases live on - composition, context, and performance thinking.
React is the payoff stage of the Frontend Development program and the heart of the dedicated React Developer program. Either way, you arrive with projects you actually built - and a certificate whose verification link shows how you earned it.
Follow a guided program, or pick a single course. Everything runs in your browser, free to start.
Comfortable JavaScript - functions, arrays, objects - and basic HTML. If you're not there yet, start with Devpuff's JavaScript Fundamentals and HTML Basics courses; the Frontend program sequences all of it in the right order automatically.
React remains the most widely used frontend library in industry job posts by a comfortable margin, and its component model shaped every alternative you might learn later. It's the safest single bet in frontend, and the concepts transfer even if you switch.
Almost everyone stumbles on the same two things - thinking in components, and understanding when state changes re-render what. Devpuff's exercises target exactly those mental models with small, focused reps rather than one giant tutorial app.

Yes. Function components and hooks throughout, matching how React is actually written today. You'll build with useState and useEffect patterns, not legacy class components.
