- * @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 - The `Date` type, the function operates on. Gets inferred from passed arguments. Allows to use extensions like [`UTCDate`](https://github.com/date-fns/utc).
- *
- * @param date - The date to be bounded
- * @param interval - The interval to bound to
- *
- * @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
