Not ultra experienced with react, but I have shot myself in the foot just because the way react is made compared to other frameworks:

- infinite loop due to re-rendering on the render function (it happens every single time i come back to react) - using useEffect when not required - nested object updates (dunno if this is still an issue) - class vs whatever the name is (className?)

Overall as another comment said I feel more fighting against react pitfalls than focusing on my application's logic. That really takes a toll in productivity as part of your brain loses a small portion of 'RAM'/cognitive load as you need to make an active effort to not shoot yourself in the foot. I guess most people get used to it, but for me it just never clicks knowing there are similarly performant frameworks with way more friendly APIs.
