数组添加新的属性，旧的数组的属性提到新的数组里去

var oldArr=[{name:‘li‘},{name:‘hi‘},{name:‘us‘}]

function loopPushObj(oldArr) {
let arr=[];
if(oldArr&&oldArr.length>0) {
    for(var i in oldArr) {
        var tempobj = {};
        tempobj = oldArr[i];
        tempobj[‘sex‘] = ‘男‘;
        arr.push(tempobj);
    }
}
return    arr;
}

 var newArr = loopPushObj(oldArr)

function loopPushObj(oldArr) {
let arr=[];
if(oldArr&&oldArr.length>0) {
    for(var i in oldArr) {
        var tempobj = {};
        tempobj = i.name;
        arr.push(tempobj);
    }
}
return    arr;
}
