for循环取出两个数组中的不同值和相同值

直接上代码

var arr1 = [数组1]
var arr2 = [数组2]
var data1 = []
var data2 = []
for(var i = 0; i < arr1.length; i++){
    var id1 = arr1[i].id;
    var isDifferent = false;
    for(var j = 0; j < arr2.length; j++){
        var id2 = arr2[j].id
        if(id1 == id2){
            data.push(arr2[j]) //这是相同的值
			isExist = true;
        }
    }
    if(!isDifferent){
        newdata.push(arr1[i]); //这是不同值
    }
}
