如何使用loadash对[object,object,object]形式的数组进行比较

Question

数组avar a = [{key:1,name:'name1'},{key:2,name:'name2'},{key:3,name:'name3'},{key:4,name:'name4'},{key:5,name:'name5'}];当数组b为 var b = [{key:1,name:'name1'}];，最后的结果应该是[{key:2,name:'name2'},{key:3,name:'name3'},{key:4,name:'name4'},{key:5,name:'name5'}]当数组b为var b = [{key:3,name:'name3'},{key:4,name:'name4'}];，最后的结果应该是[{key:1,name:'name1'},{key:2,name:'name2'},{key:5,name:'name5'}]也就是想得到数组a-数组b的结果。使用difference只对数组有效，对里面是对象并没有效var a2 = [1,2,3,4,5];        var b2 = [1,5];        console.log(_.difference(a2,b2))

Answer 1

_.differenceWith(a, b, _.isEqual)
