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

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
