如何在javascript中轻松创建空矩阵？

在Python中，您可以这样做：

[([None] * 9) for x in range(9)]

然后您会得到：

[[None, None, None, None, None, None, None, None, None],
 [None, None, None, None, None, None, None, None, None],
 [None, None, None, None, None, None, None, None, None],
 [None, None, None, None, None, None, None, None, None],
 [None, None, None, None, None, None, None, None, None],
 [None, None, None, None, None, None, None, None, None],
 [None, None, None, None, None, None, None, None, None],
 [None, None, None, None, None, None, None, None, None],
 [None, None, None, None, None, None, None, None, None]]

我如何在JavaScript中实现相同的效果？
