React

קומפוננטות, hooks ו-state לממשקים אמיתיים.

React is one of the most widely used libraries for building user interfaces, and React 19 brings Actions, the new use API and Server Components into everyday code. This track takes you from your first component to the patterns real apps rely on: props and state, lists and forms, effects and refs, context, reducers and custom hooks, and finally Suspense, Server Components, error boundaries, testing and accessibility.

You already know JavaScript, so every lesson goes straight to how React thinks, with examples from a small social app called Nova: a feed, like buttons and a leaderboard.
