TypeScript with React Learning React is a journey that progresses from core JavaScript fundamentals to advanced ecosystem tools. Beginners should first master JSX, components, props, and state. As skills grow, developers can explore hooks, state management, routing, and testing. Mastery comes with performance optimization, SSR/SSG frameworks like Next.js, and integration with TypeScript or mobile development with React Native. With consistent practice, learners can move from building small UI components to large-scale enterprise-level applications.
