* This method is like `_.indexOf` except that it iterates over elements of

* @memberOf _
* @since 0.1.0
* @category Array
* @param {Array} array The array to inspect.
* @param {*} value The value to search for.
* @param {number} [fromIndex=array.length-1] The index to search from.
* @returns {number} Returns the index of the matched value, else `-1`.
* @example
*
* _.lastIndexOf([1, 2, 1, 2], 2);
* // => 3

* // Search from the `fromIndex`.
* _.lastIndexOf([1, 2, 1, 2], 2, 2);
