## 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]) ``` 這個方法類似 `_.intersection`，除了它接受一個 comparator 調用每一個數組和值。iteratee 會傳入2個參數：((arrVal, othVal) ### 參數 1. [arrays] (...Array) 需要檢索的數組 2. [comparator] (Function) 這個函數會處理每一個元素 ### 返回值 (Array) 返回數組中共享元素的新數組 ### 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 }] ```
