Building real-world applications in React involves leveraging the capabilities of the React library and integrating it with other tools and technologies to create interactive, dynamic, and scalable web applications.

Handling API requests and data in a React application involves making asynchronous calls to APIs, fetching data, and updating the component’s state accordingly.

Redux is a state management library for JavaScript applications, particularly useful in managing the state of large and complex applications. It provides a predictable and centralized way to manage the application’s state and makes it easier to understand, debug, and maintain the state transitions.

React Router is a library that provides routing capabilities to your React applications. It allows you to create single-page applications (SPAs) with multiple views or pages, each represented by its own component.

Component composition and props drilling are concepts used in React to build complex user interfaces by combining smaller, reusable components. These concepts are integral to creating modular, maintainable, and organized applications.

In React, there are several options for styling your components and user interfaces. Here are three common approaches: inline styles, CSS classes, and CSS modules.

Creating forms in React involves building user interfaces for collecting and processing user input. React provides a convenient way to handle form elements and their values using state and event handling.

Conditional rendering is a technique in React that allows you to conditionally render different content or components based on certain conditions or states.

Event handling in React is how you manage and respond to user interactions within your components. React’s event handling system is similar to handling events in traditional HTML, but with some differences due to React’s virtual DOM and component-based architecture.

In React, component state is a mechanism that allows components to manage and maintain their own internal data that can change over time.
