React Hook useEffect has a missing dependency: 'dateParse'. Either include it or remove the dependency array. If 'dateParse' changes too often, find the parent component that defines it and wrap that definition in useCallback

React Hook useMemo has a missing dependency: 'placeholder.length'. Either include it or remove the dependency array

Mutating a value returned from 'useState()', which should not be mutated. Use the setter function to update instead

React Hook useEffect has a missing dependency: 'shouldFocus'. Either include it or remove the dependency array

React Hook useEffect has a missing dependency: 'focusedDate'. Either include it or remove the dependency array

The 'toggleVisible' function makes the dependencies of useEffect Hook (at line 74) change on every render. Move it inside the useEffect callback. Alternatively, wrap the definition of 'toggleVisible' in its own useCallback() Hook

React Hook useEffect has a missing dependency: 'getTargetElement'. Either include it or remove the dependency array

React Hook useEffect has missing dependencies: 'hasAnimations', 'offstageRight', and 'updateTransitionEnd'. Either include them or remove the dependency array
