The Core Concepts of React: A Comprehensive Summary

🌟React is a declarative library for building applications, enabling you to write code that describes what you want to happen.

🚀JSX is a syntax extension that allows you to write HTML-like code within JavaScript, making it easy to combine logic and presentation.

👨‍💻Functional components in React are simple functions that return JSX elements. They are easier to use and understand compared to class components.

🧩Class components in React have life cycle methods and are useful for managing complex state and handling side effects.

🌐React provides hooks like useState and useEffect to manage state and handle side effects in functional components.

What is the difference between functional and class components?

—Functional components are simpler and easier to use, while class components have life cycle methods and are suitable for managing complex state.

What is JSX?

—JSX is a syntax extension that allows you to write HTML-like code within JavaScript. It makes combining logic and presentation easier in React.

How do you manage state in React?

—You can use hooks like useState in functional components, or the class component's state property and setState method to manage state in React.

What are life cycle methods in React?

—Life cycle methods are special methods that are automatically called at different stages of a component's life cycle, such as mounting, updating, and unmounting.

How do you make API requests in React?

—You can use tools like the fetch API or libraries like Axios to make API requests in React. Redux can also be used for managing data and making API calls.
