/**
* @name closestTo
* @category Common Helpers
* @summary Return a date from the array closest to the given date.
*
* @description
* Return a date from the array closest to the given date.
*
* @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 dateToCompare - The date to compare with
* @param dates - The array to search
*
* @returns The date from the array closest to the given date or undefined if no valid value is given
*
* @example
* // Which date is closer to 6 September 2015: 1 January 2000 or 1 January 2030?
* const dateToCompare = new Date(2015, 8, 6)
* const result = closestTo(dateToCompare, [
* new Date(2000, 0, 1),
* new Date(2030, 0, 1)
* ])
* //=> Tue Jan 01 2030 00:00:00
