10 * This method is like `_.findIndex` except that it iterates over elements
11 * of `collection` from right to left.
12 *
13 * @static
14 * @memberOf _
15 * @since 2.0.0
16 * @category Array
17 * @param {Array} array The array to inspect.
18 * @param {Function} [predicate=_.identity] The function invoked per iteration.
19 * @param {number} [fromIndex=array.length-1] The index to search from.
20 * @returns {number} Returns the index of the found element, else `-1`.
21 * @example
22 *
23 * var users = [
24 * { 'user': 'barney', 'active': true },
25 * { 'user': 'fred', 'active': false },
26 * { 'user': 'pebbles', 'active': false }
27 * ];
28 *
29 * _.findLastIndex(users, function(o) { return o.user == 'pebbles'; });
30 * // => 2
31 *
32 * // The `_.matches` iteratee shorthand.
33 * _.findLastIndex(users, { 'user': 'barney', 'active': true });
34 * // => 0
35 *
36 * // The `_.matchesProperty` iteratee shorthand.
37 * _.findLastIndex(users, ['active', false]);
38 * // => 2
39 *
40 * // The `_.property` iteratee shorthand.
41 * _.findLastIndex(users, 'active');
42 * // => 0
