// One of my new favorite React Hook patternms is to create handler
// functions for a custom hook using `React.useMemo` instead of
// `React.useCallback`, like so:

function useBool(initialState = false) {
  const [state, setState] = React.useState(initialState)
  
  // Instead of individual React.useCallbacks gathered into an object
  // Let's memoize the whole object. Then, we can destructure the
  // methods we need in our consuming component.
