/**
 * @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       |
 *
 * @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.unit` must be 'second', 'minute', 'hour', 'day', 'month' or 'year'
 * @throws `options.locale` must contain `formatDistance` property
 *
 * @example
 * // What is the distance between 2 July 2014 and 1 January 2015?
 * const result = formatDistanceStrict(new Date(2014, 6, 2), new Date(2015, 0, 2))
 * //=> '6 months'
 *
 * @example
 * // What is the distance between 1 January 2015 00:00:15
 * // and 1 January 2015 00:00:00?
 * const result = formatDistanceStrict(
 *   new Date(2015, 0, 1, 0, 0, 15),
 *   new Date(2015, 0, 1, 0, 0, 0)
 * )
 * //=> '15 seconds'
 *
 * @example
 * // What is the distance from 1 January 2016
 * // to 1 January 2015, with a suffix?
 * const result = formatDistanceStrict(new Date(2015, 0, 1), new Date(2016, 0, 1), {
 *   addSuffix: true
 * })
 * //=> '1 year ago'
 *
 * @example
 * // What is the distance from 1 January 2016
 * // to 1 January 2015, in minutes?
 * const result = formatDistanceStrict(new Date(2016, 0, 1), new Date(2015, 0, 1), {
 *   unit: 'minute'
 * })
 * //=> '525600 minutes'
 *
 * @example
 * // What is the distance from 1 January 2015
 * // to 28 January 2015, in months, rounded up?
 * const result = formatDistanceStrict(new Date(2015, 0, 28), 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'
 * const result = formatDistanceStrict(new Date(2016, 7, 1), new Date(2015, 0, 1), {
 *   locale: eoLocale
 * })
 * //=> '1 jaro'
