+ * This method is like `_.intersection` except that it accepts `comparator`

+ * with two arguments: (arrVal, othVal).
+ *
+ * @static
+ * @memberOf _
+ * @category Array
+ * @param {...Array} [arrays] The arrays to inspect.
+ * @param {Function} [comparator] The comparator invoked per element.
+ * @returns {Array} Returns the new array of shared values.
+ * @example
+ *
+ * var objects = [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }];
+ * var others = [{ 'x': 1, 'y': 1 }, { 'x': 1, 'y': 2 }];
+ *
+ * _.intersectionWith(objects, others, _.isEqual);
+ * // => [{ 'x': 1, 'y': 2 }]
