Summary  
This chapter covers how to structure and update interfaces using components and JSX, manage data flow with props and state, and render dynamic content through conditional logic and lists.

General domain of usage  
Frontend web development

React allows you to build user interfaces using components. Each component describes a part of the UI and updates automatically when data changes.

You worked with:
- Components and JSX to structure the UI;
- Props to pass data between components;
- State to manage dynamic behavior;
- Conditional rendering and lists to display data.



These concepts form the foundation of modern frontend development.
React focuses on building the user interface. You still use JavaScript to manage logic, data, and interactions inside your components.



As applications grow, managing data and component structure becomes more complex. To improve code reliability and maintainability, developers often use tools that help catch errors early and make code easier to scale.



Further, you will learn how TypeScript enhances JavaScript and improves the development experience when building React applications.
