+ * @name constructFrom
+ * @category Generic Helpers
+ * @summary Constructs a date using the reference date and the value
+ *
+ * @description
+ * The function constructs a new date using the constructor from the reference
+ * date and the given value. It helps to build generic functions that accept
+ * date extensions.
+ *
+ * It defaults to `Date` if the passed reference date is a number or a string.
+ *
+ * @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 reference date to take constructor from
+ * @param value - The value to create the date
+ *
+ * @returns Date initialized using the given date and value
+ *
+ * @example
+ * import { constructFrom } from 'date-fns'
+ *
+ * // A function that clones a date preserving the original type
+ * function cloneDate<DateType extends Date(date: DateType): DateType {
+ *   return constructFrom(
+ *     date, // Use contrustor from the given date
+ *     date.getTime() // Use the date value to create a new date
+ *   )
+ * }
