I really like hooks. I previously spent a lot of time in HOCs, and I find hooks much simpler. But I also have problems with #5 (control flow):
The main issue I have with hooks is that I can't easily trace why updates are being triggered in my app; this makes it hard to debug performance issues. For example, my app once got really slow, and the profiler told me that a root(ish)-level component was causing a lot of re-renders. Unfortunately, that component used multiple hooks, and the only way I was able to isolate the problem was by binary-searching, deleting hooks until the re-renders stopped.

Anyone have better ways of dealing with this?
