This powerful React hook will allow you to fix your performance problems by memoizing a function and only re-computing it when necessary. You will learn how to identify performance problems from functions causing sub-components to re-render, how to memoize the functions using React's useCallback hook, and how to use the dependency array to control exactly when and how your function updates. In this new React world, hooks are here to stay, so it's best to learn them! In this tutorial I demonstrate the useCallback React hook, and I explain it very simply and in a way that is easy to understand. Enjoy!
