Creating a React JSX Component

What you'll learn

In this chapter, you will be introduced to the core concept of components, which are the building blocks of React applications. You will learn how React's component-based architecture allows you to break down the UI into smaller, reusable parts. By creating basic components using JSX, you will see how to integrate them into larger applications to build dynamic user interfaces.

You will explore how to pass data between components using props, enabling parent components to communicate with their children. Through practical examples, you will develop a deeper understanding of structuring applications where each component has a clear and defined responsibility. This focus on modularity will set the stage for building scalable React applications.

The chapter also introduces composition, where components are nested within one another to create a hierarchical structure. You will learn how to define and use properties effectively, gaining insight into React's declarative approach to UI development. These lessons will prepare you for more complex interactions as your applications grow.

Finally, you will get a glimpse of state management in React, understanding how it differs from props. You will discover that state represents data managed internally by a component, a critical concept for building interactive and dynamic applications. By the end of this chapter, you will be ready to leverage components, props, and JSX to create maintainable and reusable React applications.
