/**
* @name set
* @category Common Helpers
* @summary Set date values to a given date.
*
* @description
* Set date values to a given date.
*
* Sets time values to date from object `values`.
* A value is not set if it is undefined or null or doesn't exist in `values`.
*
* Note about bundle size: `set` does not internally use `setX` functions from date-fns but instead opts
* to use native `Date#setX` methods. If you use this function, you may not want to include the
* other `setX` functions that date-fns provides if you are concerned about the bundle size.
*
* @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 changed
* @param values - The date values to be set
*
* @returns The new date with options set
*
* @example
* // Transform 1 September 2014 into 20 October 2015 in a single line:
* const result = set(new Date(2014, 8, 20), { year: 2015, month: 9, date: 20 })
* //=> Tue Oct 20 2015 00:00:00
*
* @example
* // Set 12 PM to 1 September 2014 01:23:45 to 1 September 2014 12:00:00:
* const result = set(new Date(2014, 8, 1, 1, 23, 45), { hours: 12 })
* //=> Mon Sep 01 2014 12:23:45
