React explained
React is a JavaScript library for building interactive user interfaces from reusable components. Developers describe what the interface should show for the current data, and React updates the browser efficiently when that data changes.
Components, props and state
Components divide an interface into manageable pieces. Props pass information into a component, while state stores values that change over time. Hooks help components manage state, effects, references and shared behaviour.
Building a complete React application
Real applications add routing, forms, validation, authentication, API integration, loading states, error handling and testing. TypeScript improves maintainability by checking data shapes and component contracts.
How to learn React
Build a strong base in HTML, CSS and modern JavaScript before React. Then create progressively larger projects that consume APIs, manage state and deploy to the web. Learn performance and testing after the fundamentals are comfortable.
