Optimizing Rendering Performance in React

We are going to use some performance optimization techniques to fix re-rendering issues in our React app that we discovered after performance profiling using React Developer Tools. React Hooks such as useCallback and memo play a big role here. Let's see how they can help here.

Obviously such optimizations are not necessary with a small number of re-rendered children as long as they are not too heavy. But at what point does memoizing become important? 100 items, 1.000 items or maybe 100.000 items? Share your thoughts here ✌

This was a great video. I am brand now to full stack development. Days old. I looked up a video he mentioned to learn about profiling and performance to speed up a build. I looked up some stuff and I go here to your video. The problem for me is I think I am a little too new to full appreciate it yet. I took notes on everything you said and I have bookmarked this. Thank you.

I've seen code like this in my codebase at work and didn't really get why it was necessary, this kinda makes a lot of sense
