Solution

/**
 * @param {number} hour
 * @param {number} minutes
 * @return {number}
 */
var angleClock = function(hour, minutes) {
  const hourAngle = (hour % 12 + minutes / 60) * 30;
  const minuteAngle = minutes * 6;
  const angle = Math.abs(hourAngle - minuteAngle);
  return Math.min(angle, 360 - angle);
};
