   * @name formatDistanceStrict
   * @category Common Helpers
   * @summary Return the distance between the given dates in words.
   *
   * @description
   * Return the distance between the given dates in words, using strict units.
   * This is like `formatDistance`, but does not use helpers like 'almost', 'over',
   * 'less than' and the like.
   *
   * | Distance between dates | Result              |
   * |------------------------|---------------------|
   * | 0 ... 59 secs          | [0..59] seconds     |
   * | 1 ... 59 mins          | [1..59] minutes     |
   * | 1 ... 23 hrs           | [1..23] hours       |
   * | 1 ... 29 days          | [1..29] days        |
   * | 1 ... 11 months        | [1..11] months      |
   * | 1 ... N years          | [1..N]  years       |
   *
   * @param {Date|String|Number} date - the date
   * @param {Date|String|Number} baseDate - the date to compare with
   * @param {Options} [options] - the object with options. See [Options]{@link https://date-fns.org/docs/Options}
   * @param {0|1|2} [options.additionalDigits=2] - passed to `toDate`. See [toDate]{@link https://date-fns.org/docs/toDate}
   * @param {Boolean} [options.addSuffix=false] - result indicates if the second date is earlier or later than the first
   * @param {'second'|'minute'|'hour'|'day'|'month'|'year'} [options.unit] - if specified, will force a unit
   * @param {'floor'|'ceil'|'round'} [options.roundingMethod='round'] - which way to round partial units
   * @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} `options.additionalDigits` must be 0, 1 or 2
   * @throws {RangeError} `options.roundingMethod` must be 'floor', 'ceil' or 'round'
   * @throws {RangeError} `options.unit` must be 'second', 'minute', 'hour', 'day', 'month' or 'year'
   * @throws {RangeError} `options.locale` must contain `formatDistance` property
   *

   *   new Date(2015, 0, 1),
   *   {unit: 'minute'}
   * )
   * //=> '525600 minutes'
   *
   * @example
   * // What is the distance from 1 January 2016
   * // to 28 January 2015, in months, rounded up?
   * var result = formatDistanceStrict(

   *   new Date(2015, 0, 1),
   *   {unit: 'month', roundingMethod: 'ceil'}
   * )
   * //=> '1 month'
   *
   * @example
   * // What is the distance between 1 August 2016 and 1 January 2015 in Esperanto?
   * import { eoLocale } from 'date-fns/locale/eo'
