const touchSupported = () => {
  ('ontouchstart' in window || window.DocumentTouch && document instanceof window.DocumentTouch);
}

console.log(touchSupported());
// Result: will return true if touch events are supported, false if not

const touchSupported = () => (
  'ontouchstart' in window || window.DocumentTouch && document instanceof window.DocumentTouch;
)
