js实现数组的随机排序

// 数组随机排序
let arrpx = [1,2,3,4,6,5,7,9,8];
function randpx(arr){
    for(let i=0;i<arr.length;i++){
        let rand = parseInt(Math.random()*arr.length);
        let temp = arr[rand];
        arr[rand] = arr[i];
        arr[i] = temp;
    }
	return arr;
}
console.log(randpx(arrpx));
// sort排序
let arrpx2 = [1,2,3,4,5,6,7,8,9,10];
arrpx2.sort(function(){
	return Math.random() - 0.5;
})
console.log(arrpx2);
