/**
 * This method is like `findIndex` except that it iterates over elements
 * of `collection` from right to left.
 *
 * @since 5.2.0
 * @category Array
 * @param array The array to inspect.
 * @param predicate The function invoked per iteration.
 * @param fromIndex The index to search from.
 * @returns {number} Returns the index of the found element, else `-1`.
 * @example
 *
 * ```js
 *
 * var users = [
 *   { 'user': 'barney',  'active': true },
 *   { 'user': 'fred',    'active': false },
 *   { 'user': 'pebbles', 'active': false }
 * ];
 *
 * findLastIndex(users, function(o) { return o.user == 'pebbles'; });
 * // => 2
 *
 * // The `matches` iteratee shorthand.
 * findLastIndex(users, { 'user': 'barney', 'active': true });
 * // => 0
 *
 * // The `matchesProperty` iteratee shorthand.
 * findLastIndex(users, ['active', false]);
 * // => 2
 *
 * // The `property` iteratee shorthand.
 * findLastIndex(users, 'active');
 * // => 0
 *
 * ```
