Web development has changed significantly in recent years. A web developer should not only know the basics of HTML, CSS, and JavaScript but also be proficient in frameworks such as Angular, React, and Vue. These frameworks make web development easier, enabling developers to focus on the application logic.

This course is designed for newcomers to React and experienced React developers alike. You’ll start by learning the most fundamental concept in React—components. Specifically, you’ll learn about function components. You’ll then learn how to manage application state and side effects. You’ll then learn about the useMemo hook to boost an application’s performance. You’ll learn about the useContext hook which enables us to perform area updates in our application. Finally, you’ll learn how to create custom hooks in React.

After completing this course, you can develop frontend applications with React. You’ll be able to develop complex web applications faster because React makes the process much easier.
