Lodash/JavaScript:比较两个集合并返回差异 [英] Lodash / javascript : Compare two collections and return the differences

问题描述

我有两个对象数组:

表中的元素不是原始值，而是复杂的对象.

the element of my table are not primitive value, but complexe objects.

array1 = [obj1,obj2,obj3,obj4]
array2 = [obj5,obj5,obj6,obj7]

我想比较两个数组，看看array2的元素已经存在于array1中，然后创建一个新的差异数组.

I would like to compare two arrays and see of the elements of array 2 are already present in array1 then create a new array of the difference.

有什么建议吗?

推荐答案

var presents = _.intersectionWith(array1, array2, _.isEqual);
var dif = _.differenceWith(array1, array2, _.isEqual);
