useCallback

Removing dependencies: functions

• ESLint plugin React Hooks exhaustive deps rule will give you guidance.

Heuristic to keep the dependency array small: To remove functions from the dependency array try the following steps (in order):

1. Function into useEffect hook
2. Function out of component
3. Function with useCallback (see this CodeSandBox of our code (JS) for an example)

• Note: useState setter functions may be ommitted from the dependency array. React guarrantees that their identity will stay stable across re-renders for the lifetime of the component.
