 *
 * If the argument is an instance of Date, the function returns its clone.

 * If the argument is a number, it is treated as a timestamp.

 * If an argument is a string, the function tries to parse it.

 * If the argument is null, it is treated as an invalid date.

 *
 * **Note**: *all* Date arguments passed to any *date-fns* function is processed by `toDate`.
 * All *date-fns* functions will throw `RangeError` if `options.additionalDigits` is not 0, 1, 2 or undefined.

 * Values will be assigned to the date in the ascending order of its unit's priority.
 * Units of an equal priority overwrite each other in the order of appearance.
 *
 * If no values of higher priority are parsed (e.g. when parsing string 'January 1st' without a year),
 * the values will be taken from 3rd argument `baseDate` which works as a context of parsing.
 *
 * `baseDate` must be passed for correct work of the function.
 * If you're not sure which `baseDate` to supply, create a new instance of Date:
 * `parse('02/11/2014', 'MM/DD/YYYY', new Date())`
 * In this case parsing will be done in the context of the current date.
 * If `baseDate` is `Invalid Date` or a value not convertible to valid `Date`,
 * then `Invalid Date` will be returned.
 *
 * Also, `parse` unfolds long formats like those in [format]{@link https://date-fns.org/docs/format}:
