11 * This method is like `_.indexOf` except that it iterates over elements of
12 * `array` from right to left.
13 *
14 * @static
15 * @memberOf _
16 * @since 0.1.0
17 * @category Array
18 * @param {Array} array The array to inspect.
19 * @param {*} value The value to search for.
20 * @param {number} [fromIndex=array.length-1] The index to search from.
21 * @returns {number} Returns the index of the matched value, else `-1`.
22 * @example
23 *
24 * _.lastIndexOf([1, 2, 1, 2], 2);
25 * // => 3
26 *
27 * // Search from the `fromIndex`.
28 * _.lastIndexOf([1, 2, 1, 2], 2, 2);
29 * // => 1
