Скачать или смотреть How to Use the useCallback Hook in React for Improved Performance |

In this video, you'll learn about the useCallback hook in React. The useCallback hook allows you to cache a function so that it doesn't get recreated every time your component renders. This can be useful for performance reasons, especially if your function is expensive to create.

We'll start by looking at a simple example of how to use useCallback. Then, we'll compare useCallback with the useMemo hook, and see when you should use each one.

By the end of this video, you'll have a good understanding of how to use useCallback in your React code.
