+ * @name eachMinuteOfInterval
+ * @category Interval Helpers
+ * @summary Return the array of minutes within the specified time interval.
+ *
+ * @description
+ * Returns the array of minutes 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 starts of minutes from the hour of the interval start to the hour of the interval end
+ * @throws {TypeError} 1 argument requie value should be more than 1.
+ * @returns {Date[]} the array withred
+ * @throws {RangeError} `options.step` must be a number equal or 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 minute between 14 October 2020, 13:00 and 14 October 2020, 13:03
+ * const result = eachMinuteOfInterval({
+ *   start: new Date(2014, 9, 14, 13),
