I believe to be able to understand these types of problems and gain knowledge about the same. It requires to you build a project and keep experimenting. Like we have all learnt closures but couldn't guess that it is being used here.

Core fundamental concepts are everywhere. They are the foundation of any good software. The aim with the content on this channel is to help fellow engineers understand the concepts better and show real world scenarios.

If the child component at the bottom re-renders as soon as the prop onMount changes (which is every render), none of this is needed, right ? It would have a fresh onMount function every time, there by fresh filePaths Is this a library/functionality restriction? Child re-rendering on prop change is fundamental react behavior. Good video though 👍

Yes, it is a restriction that it doesn't call the onMount on every re-render. If it calls then it would fail the purpose of onMount. Glad you liked the video.
