@@ -242,11 +242,16 @@ Stores the result `A` of an effect in state. The state is provided as `Pot[A]`,
 
 Note that all versions either have dependencies or are executed `onMount`. It doesn't make sense to execute the effect on each render since its completion will alter state and force a rerender, which would provoke a render loop. The naming keeps the `WithDeps`, even though it's redundant, for consistency with the `useEffect` family of hooks.
 
+Also note that when dependencies change, the hook value will revert to `Pending` until the new effect completes. If this is undesireable, there are `useEffectKeepResult*` variants which will instead keep the hook value as `Ready(oldValue)` until the new effect completes.
