+ * @name clamp
+ * @category Interval Helpers
+ * @summary Return a date bounded by the start and the end of the given interval.
+ *
+ * @description
+ * Clamps a date to the lower bound with the start of the interval and the upper
+ * bound with the end of the interval.
+ *
+ * - When the date is less than the start of the interval, the start is returned.
+ * - When the date is greater than the end of the interval, the end is returned.
+ * - Otherwise the date is returned.
+ *
+ * @typeParam DateType - Date argument type.
+ * @typeParam IntervalType - Interval argument type.
+ * @typeParam Options - Options type.
+ *
+ * @param date - The date to be bounded
+ * @param interval - The interval to bound to
+ * @param options - An object with options
+ *
+ * @returns The date bounded by the start and the end of the interval
+ *
+ * @example
+ * // What is Mar 21, 2021 bounded to an interval starting at Mar 22, 2021 and ending at Apr 01, 2021
+ * const result = clamp(new Date(2021, 2, 21), {
+ *   start: new Date(2021, 2, 22),
+ *   end: new Date(2021, 3, 1),
+ * })
+ * //=> Mon Mar 22 2021 00:00:00
