javascript - 分形数组语法

Question

我有一个包含 4 个值的数组，每个数组中有 6 个数组，如下所示 -

[0,0,0,0,[],[],[],[],[],[]]

在每个数组中，我放置了该对象的副本来创建它 -

[0,0,0,0,[[0,0,0,0,[],[],[],[],[],[]]],[[0,0,0, 0,[],[],[],[],[],[]]],[[0,0,0,0,[],[],[],[],[],[]] ],[[0,0,0,0,[],[],[],[],[],[]]],[[0,0,0,0,[],[],[] ,[],[],[]]],[[0,0,0,0,[],[],[],[],[],[]]]]

我对每个数组重复了该过程。

再一次。

总共 1[i] + 6[i][i] + 36[i][i][i] + 216[i][i][i] + 1296[i][i][i ][我]

我的阵列正在做我想要的事情，是的，它工作正常，性能或任何方面都没有问题! 但是!!!看起来像这样——

var Pl = [0,0,0,0,[0,0,0,0,[0,0,0,0,[0,0,0,0,[],[],[],[],[],[]],[0,0,0,0,[],[],[],[],[],[]],[0,0,0,0,[],[],[],[],[],[]],[0,0,0,0,[],[],[],[],[],[]],[0,0,0,0,[],[],[],[],[],[]],[0,0,0,0,[],[],[],[],[],[]]],

我可以分配更小吗？并保持在每个数组(全部 1500 个数组)上存储“对象值”的能力。使用脚本将其缩小会降低效率吗？

谢谢!

Answer 1

你可以像这样创建一个递归函数。

function createArrayWithDepth(depth) {
  if(depth == 0)
    return [];
  else {
    var subArray = createArrayWithDepth(depth - 1);
    return [0, 0, 0, 0, subArray, subArray, subArray, subArray, subArray, subArray];
  }
}

var array = createArrayWithDepth(3);

console.log(array);
