- * @summary Return the latest of the given dates.
- *
- * @description
- * Return the latest of the given dates.
- *
- * @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).
- * @typeParam ResultDate - The result `Date` type, it is the type returned from the context function if it is passed, or inferred from the arguments.
- *
- * @param dates - The dates to compare
- *
- * @returns The latest of the dates
- *
- * @example
- * // Which of these dates is the latest?
- * const result = max([
- * new Date(1989, 6, 10),
- * new Date(1987, 1, 11),
- * new Date(1995, 6, 2),
- * new Date(1990, 0, 1)
