s1=[[[1, 10],[3,5.12],[5,13.1],[7,3],[9,8],[11,2]]]
现在什么是s1?数组 ?二维数组?然后如何创建它?
答案 0 :(得分:1)
s1是变量,包含数组,包含数组,包含数组:)
我们可以像这样简化您的代码:
s1=[ //this is first Array
[ // this is first and last element of previous Array, and it is Array too
[1, 10], // elements of Array, they are Arrays too and contain 2 numbers
[3,5.12],
[5,13.1],
[7,3],
[9,8],
[11,2]
]
];
如果我们想获得一个数字,例如5,你可以这样做:
console.log(s1[0][2][0]); // 5
