🔄 Why does your useEffect keep running endlessly? 🤔
At first, your code looks fine… but there’s a hidden trap:
❌ Objects, arrays, and functions aren’t like primitives.
Every render creates a new reference, so React thinks the dependency changed—even if the content is identical. The result? Your effect keeps firing on repeat.
âś… The fix: memoization (useMemo or useCallback).
With stable references, React only reruns the effect when it actually should.
đź”§ How I avoid the trap:
👉 Remember: non-primitives are passed by reference, not by value.
👉 Memoize values/functions when including them in dependency arrays.
👉 Move them outside the render if they don’t depend on props or state.
⚡ Stable references = fewer re-renders + fewer bugs. 🚀
