LeetCode but only for React devs — feedback welcome

I built ReactGrind because every time I prepped for React interviews, I ended up solving generic DSA problems on LeetCode that had nothing to do with what I'd actually be asked — hooks gotchas, state management bugs, re-render performance, compound components.

ReactGrind has 25+ hand-crafted problems list (and growing) that mirror real interview and real-world scenarios — things like building a debounced search, a virtualized table, a wizard-style form state machine, and a realtime kanban board. Everything runs and tests in-browser, no setup.

Would love feedback on which problem categories to add next. Happy to answer anything!
