Solved: Common useEffect anti-patterns I see in code reviews (and how to fix them)

🚀 Executive Summary TL;DR: Infinite loops in React’s useEffect often stem from referential equality issues with non-primitive dependencies defined within components. Solutions range from hoisting static values and memoizing dynamic ones with useMemo/useCallback to abstracting data fetching entirely using custom hooks or libraries like TanStack Query. 🎯 Key Takeaways JavaScript’s referential equality for non-primitive types (objects, arrays, functions) is the root cause of many useEffect infinite loops. Defining objects or functions inside a component and including them in useEffect’s dependency array will cause the effect to re-run on every render due to new references being created. Solutions include hoisting static dependencies outside the component, using useMemo for objects/arrays and useCallback for functions to stabilize references, or abstracting data fetching logic with custom hooks or libraries like TanStack Query for a more robust, declarative approach.
