This video explains how you can create your own useTimeout hook in react.
The useTimeout custom hook in React provides a way to execute a function after a specified delay. It simplifies the use of setTimeout by managing the timer lifecycle, ensuring the timer is cleared when the component unmounts or the delay changes. This hook is useful for scenarios where you need to perform delayed actions like showing notifications or triggering animations.

Thanks for this great walkthrough. Quick question though, why do we have to set the ref initially to null?

We can set the cb function too initially as ref. Not an issue. Both are correct
