Answer 1

&nbsp;&nbsp;&nbsp;&nbsp;var&nbsp;arr1&nbsp;=&nbsp;[1,&nbsp;2,&nbsp;3,&nbsp;4],&nbsp;arr2&nbsp;=&nbsp;[5,&nbsp;6,&nbsp;7,&nbsp;8]; &nbsp;&nbsp;&nbsp;&nbsp;var&nbsp;newArr&nbsp;=&nbsp;[]; &nbsp;&nbsp;&nbsp;&nbsp;for&nbsp;(var&nbsp;i&nbsp;=&nbsp;0;&nbsp;i&nbsp;<&nbsp;arr1.length;&nbsp;i++)&nbsp;newArr[i]&nbsp;=&nbsp;arr1[Math.floor(Math.random()&nbsp;*&nbsp;arr1.length)]&nbsp;+&nbsp;arr2[Math.floor(Math.random()&nbsp;*&nbsp;arr2.length)] &nbsp;&nbsp;&nbsp;&nbsp;console.log(newArr)

Answer 2

可以用math.random函数实现用数组length获取随机数的最大值，就可以分别获取两个数组里的随机数了
