intersectionWith

js
_.intersectionWith([arrays], [comparator])

此方法与 _.intersection 类似,不同之处在于它接受 comparator,调用该方法可比较 arrays 的元素。结果值的顺序和引用由第一个数组决定。比较器使用两个参数调用:(arrVal, othVal)。

¥This method is like _.intersection except that it accepts comparator which is invoked to compare elements of arrays. The order and references of result values are determined by the first array. The comparator is invoked with two arguments: (arrVal, othVal).
