Jammming: Is useCallback necessary?

I’m wondering if useCallback is strictly necessary for this project? I’m doing the full stack career path and we haven’t learnt about that function yet. After tooling around with the project and hitting a few walls, I ended up looking at the example code and useCallback seems to solve a lot of my problems.

That said, after a lot of research, the react community seems fairly aligned that usecallback isn’t necessary but can help with performance (not an issue for the jammming project).
