Js比较对Object类型进行排序

<script>
    var data=[{name:"121",age:"18",year:"2018"},{name:"132",age:"16",year:"2019"}]
    /**
     * 创建比较参数函数
     * @param propertyName 属性名
     * @returns {Function} 返回比较函数
     */
    function compareFunction(propertyName){
        return function (src,tar) {
            //获取比较的值
            var v1=src[propertyName];
            var v2=tar[propertyName];
            if(v1>v2){
                return 1;
            }
            if(v1<v2){
                return -1;
            }
            return 0;
        };
    }
    //按照age进行比较
    data.sort(compareFunction("age"));
    alert(data[0].name);
    //按照year进行比较
    data.sort(compareFunction("year"));
    alert(data[0].name)
