Great write-up. As someone still getting my bearings with intermediate React, the distinction you made about not over-using useMemo for cheap computations like string concatenation clears up a lot of conflicting advice I’ve seen online.
I do have a practical question regarding state collocation versus using atomic state libraries like Zustand or Jotai. For a beginner trying to build good habits, at what point does a project actually warrant moving away from standard prop-drilling or basic context and introducing a third-party state manager? Is there a specific architectural "tipping point" or metric you look for before making that jump?
Thanks for sharing these insights!
