Introduction to React
This topic introduces students to React as a library, explaining its core philosophy and helping them get a working project set up so they can start writing React code right away.
This topic covers the building blocks of any React application — components — and how data is passed between them to create reusable, modular UI pieces.
This topic introduces state as a way for components to store and manage changing data, along with how React handles user interactions like clicks and inputs.
This topic goes deep into React Hooks beyond the basics, covering essential hooks for managing side effects, performance, and reusable logic — critical knowledge for building real-world React applications.
This topic focuses on handling user input through forms, a common requirement in most real-world applications, covering both control patterns and validation.
This topic introduces client-side routing in React, allowing applications to have multiple pages/views without full page reloads, which is essential for building single-page applications.
This topic covers how to manage state across an entire application rather than just within individual components, addressing challenges that arise as apps grow larger.
This topic introduces the basics of testing React components, helping students ensure their applications work correctly and remain stable as they grow.
This final topic covers how to prepare a React application for production and deploy it live, followed by a capstone project that ties together everything learned in the course.
This lesson covers the useRef hook, showing students how to directly access DOM elements and persist values across renders without triggering re-renders.
