俩个数组去重

#俩个数组去重 （键值对类型的）

var arr=[{"id":1,"value":1},{"id":2,"value":2},{"id":3,"value":3}]；
var arr1=[{"id":1,"value":1},{"id":4,"value":4},{"id":5,"value":5}]；
//带键值对的用 for in
for(var i in arr){
		for(var k in arr1){
		if(arr[i].id == arr1[k].id){
			arr1.splice(k,1)
		}
	 }
}
console.log(arr1);
//输出结果为  [{id: 4, value: 4}1: {id: 5, value: 5}]
