+ * @description
+ * Return the array of hours within the specified time interval.
+ *
+ * @param {Interval} interval - the interval. See [Interval]{@link https://date-fns.org/docs/Interval}
+ * @param {Object} [options] - an object with options.
+ * @param {Number} [options.step=1] - the step to increment by. The value should be more than 1.
+ * @returns {Date[]} the array with starts of hours from the hour of the interval start to the hour of the interval end
+ * @throws {TypeError} 1 argument required
+ * @throws {RangeError} `options.step` must be a number greater than 1
+ * @throws {RangeError} The start of an interval cannot be after its end
+ * @throws {RangeError} Date in interval cannot be `Invalid Date`
+ *
+ * @example
+ * // Each hour between 6 October 2014, 12:00 and 6 October 2014, 15:00
+ * const result = eachHourOfInterval({
