> fun fact: You Might Not Need an Effect was inspired by a little investigation. i spot-checked random 128 useEffect calls in the Meta codebase, classified them into several groups, and 59 out 128 were unnecessary.
My own experience, on a much more limited scale, is similar. Especially developers new to React tend to write more useEffects than actually necessary. These often add unnecessary complexity and make the component much harder to understand.
