/**
* @name formatRelative
* @category Common Helpers
* @summary Represent the date in words relative to the given base date.
*
* @description
* Represent the date in words relative to the given base date.
*
* | Distance to the base date | Result |
* |---------------------------|---------------------------|
* | Previous 6 days | last Sunday at 04:30 AM |
* | Last day | yesterday at 04:30 AM |
* | Same day | today at 04:30 AM |
* | Next day | tomorrow at 04:30 AM |
* | Next 6 days | Sunday at 04:30 AM |
* | Other | 12/31/2017 |
*
* @param {Date|Number} date - the date to format
* @param {Date|Number} baseDate - the date to compare with
* @param {Object} [options] - an object with options.
* @param {Locale} [options.locale=defaultLocale] - the locale object. See [Locale]{@link https://date-fns.org/docs/Locale}
* @param {0|1|2|3|4|5|6} [options.weekStartsOn=0] - the index of the first day of the week (0 - Sunday)
* @returns {String} the date in words
* @throws {TypeError} 2 arguments required
* @throws {RangeError} `date` must not be Invalid Date
* @throws {RangeError} `baseDate` must not be Invalid Date
* @throws {RangeError} `options.weekStartsOn` must be between 0 and 6
* @throws {RangeError} `options.locale` must contain `localize` property
* @throws {RangeError} `options.locale` must contain `formatLong` property
* @throws {RangeError} `options.locale` must contain `formatRelative` property
*
* @example
* // Represent the date of 6 days ago in words relative to the given base date. In this example, today is Wednesday
* const result = formatRelative(addDays(new Date(), -6), new Date())
* //=> "last Thursday at 12:45 AM"
