JS对对象进行排序

// var obj =
    var persons = [
        {name:"lily1",sex:"女",age:18},
        {name:"lily2",sex:"女",age:19},
        {name:"lily3",sex:"女",age:11},
        {name:"lily4",sex:"女",age:28},
        {name:"lily5",sex:"女",age:22},
        ]
    
    //请对数组persons进行按照年龄升序排序
    persons.sort(function (a,b) {
        if (a.age>b.age) {
            return 1;
        }else if(a.age<b.age){
            return -1;
        }else{
            return 0;
        }
    })
    console.log(persons);
