javascript 如何对两个数组进行比较

Question

数组a[{key:1,name:'name1'},{key:2,name:'name2'},{key:3,name:'name3'},{key:4,name:'name4'},{key:5,name:'name5'}]数组b是在数组a的一部分[{key:1,name:'name1'},{key:2,name:'name2'}]数组c是在数组b的基础上进行修改[{key:1,name:'name11'},{key:22,name:'name22'}]现在需要最后的结果为key:1被修改，key:2被删除，key:3，key:4，key:5无变化保留，key:22被添加[{key:1,name:'name11'},{key:3,name:'name3'},{key:4,name:'name4'},{key:5,name:'name5'},{key:22,name:'name22'}]请问一下如何才能实现这个逻辑

Answer 1

使用lodash 的_.differenceWith(a, b, _.isEqual).concat(c)解决了
