/**
 * @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)'
