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.

To create effects during the component update

To manage cleanup and side effects in a functional component


What is the primary purpose of the `useEffect` hook in the React component?

What is the primary purpose of the <code>useEffect</code> hook in the React component?

The effect is created once during the initial mount.

The effect is created for any changes in the `a` and `b` elements.

The effect is created only if `a` and `b` are both `true`.

The effect is created only during the unmount.

What triggers the creation of the effect when some dependencies are provided in `useEffect(fn, [a, b])`?

What triggers the creation of the effect when some dependencies are provided in <code>useEffect(fn, [a, b])</code>?

What is the general order of execution for the destroy and create functions in the `useEffect` hook?
