 * @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 date
 * @param baseDate - The date to compare with
 * @param options - An object with options
 *
 * @returns The distance in words
 *
 * @throws `date` must not be Invalid Date
 * @throws `baseDate` must not be Invalid Date
 * @throws `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), {
