* Return the distance between the given dates in words.
*
* | Distance between dates | Result |
* |-------------------------------------------------------------------|---------------------|
* | 0 ... 30 secs | less than a minute |
* | 30 secs ... 1 min 30 secs | 1 minute |
* | 1 min 30 secs ... 44 mins 30 secs | [2..44] minutes |
* | 44 mins ... 30 secs ... 89 mins 30 secs | about 1 hour |
* | 89 mins 30 secs ... 23 hrs 59 mins 30 secs | about [2..24] hours |
* | 23 hrs 59 mins 30 secs ... 41 hrs 59 mins 30 secs | 1 day |
* | 41 hrs 59 mins 30 secs ... 29 days 23 hrs 59 mins 30 secs | [2..30] days |
* | 29 days 23 hrs 59 mins 30 secs ... 44 days 23 hrs 59 mins 30 secs | about 1 month |
* | 44 days 23 hrs 59 mins 30 secs ... 59 days 23 hrs 59 mins 30 secs | about 2 months |
* | 59 days 23 hrs 59 mins 30 secs ... 1 yr | [2..12] months |
* | 1 yr ... 1 yr 3 months | about 1 year |
* | 1 yr 3 months ... 1 yr 9 month s | over 1 year |
* | 1 yr 9 months ... 2 yrs | almost 2 years |
* | N yrs ... N yrs 3 months | about N years |
* | N yrs 3 months ... N yrs 9 months | over N years |

* |------------------------|----------------------|
* | 0 secs ... 5 secs | less than 5 seconds |
* | 5 secs ... 10 secs | less than 10 seconds |
* | 10 secs ... 20 secs | less than 20 seconds |
* | 20 secs ... 40 secs | half a minute |
* | 40 secs ... 60 secs | less than a minute |
* | 60 secs ... 90 secs | 1 minute |
*
* @param {Date|Number} date - the date
* @param {Date|Number} baseDate - the date to compare with
* @param {Object} [options] - an object with options.
* @param {Boolean} [options.includeSeconds=false] - distances less than a minute are more detailed
* @param {Boolean} [options.addSuffix=false] - result indicates if the second date is earlier or later than the first
* @param {Locale} [options.locale=defaultLocale] - the locale object. See [Locale]{@link https://date-fns.org/docs/Locale}
* @returns {String} the distance 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.locale` must contain `formatDistance` property
*
* @example
* // What is the distance between 2 July 2014 and 1 January 2015?
* const result = formatDistance(new Date(2014, 6, 2), new Date(2015, 0, 1))
* //=> '6 months'
*
* @example
* // What is the distance between 1 January 2015 00:00:15
* // and 1 January 2015 00:00:00, including seconds?
* const result = formatDistance(
* new Date(2015, 0, 1, 0, 0, 15),
* new Date(2015, 0, 1, 0, 0, 0),
* { includeSeconds: true }
* )
* //=> 'less than 20 seconds'
*
* @example
* // What is the distance from 1 January 2016
* // to 1 January 2015, with a suffix?
* const result = formatDistance(new Date(2015, 0, 1), new Date(2016, 0, 1), {
* addSuffix: true
* })
* //=> 'about 1 year ago'
*
* @example
* // What is the distance between 1 August 2016 and 1 January 2015 in Esperanto?
* import { eoLocale } from 'date-fns/locale/eo'
* const result = formatDistance(new Date(2016, 7, 1), new Date(2015, 0, 1), {
