## intersectionWith + [link](./intersectionWith "Link to this entry.") + [source](https://github.com/lodash/lodash/blob/4.5.0正式版/lodash.src.js#L6145 "View in source.") + [npm](https://www.npmjs.com/package/lodash.intersectionwith "See the npm package.") ``` _.intersectionWith([arrays], [comparator]) ``` 这个方法类似 `_.intersection`，除了它接受一个 comparator 调用每一个数组和值。iteratee 会传入2个参数：((arrVal, othVal) ### 参数 1. [arrays] (...Array) 需要检索的数组 2. [comparator] (Function) 这个函数会处理每一个元素 ### 返回值 (Array) 返回数组中共享元素的新数组 ### 示例 ``` 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 }] ```
