js从一个对象数组中根据属性值大小排序

<script type="text/javascript">
        var sdts = [
            {name:"小明",age:30},
            {name:"小红",age:20},
            {name:"小花",age:40}
        ]
        function compare(property,desc) {
            return function (a, b) {
                var value1 = a[property];
                var value2 = b[property];
                if(desc==true){
                    // 升序排列
                    return value1 - value2;
                }else{
                    // 降序排列
                    return value2 - value1;
                }
            }
        }
        // console.log(sdts.sort(compare("age",true)))
        console.log(sdts.sort(compare("age",false)))
    </script>
