/**
* @name transpose
* @category Generic Helpers
* @summary Transpose the date to the given constructor.
*
* @description
* The function transposes the date to the given constructor. It helps you
* to transpose the date in the system time zone to say `UTCDate` or any other
* date extension.
*
* @typeParam DateInputType - The input `Date` type derived from the passed argument.
* @typeParam DateOutputType - The output `Date` type derived from the passed constructor.
*
* @param fromDate - The date to use values from
* @param constructor - The date constructor to use
*
* @returns Date transposed to the given constructor
*
* @example
* // Create July 10, 2022 00:00 in locale time zone
* const date = new Date(2022, 6, 10)
* //=> 'Sun Jul 10 2022 00:00:00 GMT+0800 (Singapore Standard Time)'
*
* @example
* // Transpose the date to July 10, 2022 00:00 in UTC
* transpose(date, UTCDate)
* //=> 'Sun Jul 10 2022 00:00:00 GMT+0000 (Coordinated Universal Time)'
