+/**
+ * This method is like `findIndex` except that it iterates over elements
+ * of `collection` from right to left.
+ *
+ * @since 2.0.0
+ * @category Array
+ * @param {Array} array The array to inspect.
+ * @param {Function} predicate The function invoked per iteration.
+ * @param {number} [fromIndex=array.length-1] The index to search from.
+ * @returns {number} Returns the index of the found element, else `-1`.
+ * @see find, findIndex, findKey, findLast, findLastKey
+ * @example
+ *
+ * const users = [
+ *   { 'user': 'barney',  'active': true },
+ *   { 'user': 'fred',    'active': false },
+ *   { 'user': 'pebbles', 'active': false }
+ * ]
+ *
+ * findLastIndex(users, ({ user }) => user == 'pebbles')
+ * // => 2
