1. Math.max()

var dataAP = [65, 104, 83, 83, 83, 78, 67, 83, 90, 76];
var  Max= Math.max(...dataPie1) //Max = 104

1. 轮回比较

var Max = dataAP[0];

        for(var i = 1; i < dataAP.length; i++) {
            let cur = dataAP[i];
            cur > Max ? Max = cur : null
        }
        // Max = 104

注重：项目用Math.max()运行在ie11会报错，应该是ie兼容es5的题目，横竖我的是报错了+_+
