JavaScript求数组最大值常用方法

    let ary = [1,2,22,3,99,100],maxNum = ary[0]
     function getMaxNum(ary){
 for(let i = 1,len = ary.length;i ary[i]?null:maxNum = ary[i];
 }
 return maxNum
    }
    console.log(getMaxNum(ary))

    let ary = [1,2,22,3,99,100],
    maxNum = eval(`Math.max(${ary.toString()})`);

    let ary = [1,2,22,3,99,100]；
    maxNum = Math.max.apply(null,ary)

    let ary = [1,2,22,3,99,100],
    maxNum = ary.sort((a,b)=>b-a);

tips:数组的sort方法要是不写后面的return，用默认值得花返回来的顺序不对

     let ary = [1,2,22,3,99,100],
    maxNum = Math.max(...ary)
