You could loop through each array and declare new arrays for each element,
also
This is kinda clumsy - so I'm sure others will post a better solution.-
where I will take notes.
But the point is: its really an array of arrays [of arrays].... rather than
a single multidimensional array.

If you already had an array called 'a' with an array at index 2 and
another array at that array's index 2, then you could create an array at
index 2 of that last array.

But you haven't, so you have a script error. Also, the built-in array
object has a capital 'A' (to signify that you can use it as a
constructor perhaps).

To save on typing and potential typos, use an initialiser:

var a = [];
a[2] = [];
a[2][2] = [];
a[2][2][2] = [];
A one dimension array 1x3:

var a = ['A', 'B', 'C'];
A two dimension array 2x3:

var a = [
['A', 'B', 'C'],
['D', 'E', 'F']
];
A three dimension array 2x3x3:

var a = [
[
['a','b','c'],
['d','d','f'],
['g','h','i']
],
[
['j','k','l'],
['m','n','o'],
['p','q','r']
]
]

alert( a[0][1][2] ); // shows f
Keep going and it gets much harder to read...

See the samples of 2D and 3D arrays emulation at

thank u friends

I think that Rob knows, without reading further, what this post says but
a is not a "two dimension array" as it is a simple array that has arrays
as members. Javascript arrays are linear in fashion and as such you
can't have multi-dimensional arrays.

Sorry Rob, but I had to post for posterity sake :)

That's fine. Others may say that a is a 2D array (matrix) that is
constructed using 2 one-dimensional JavaScript Array objects. :-)

Tis true, but VK might say that "RobG says JS has a multi-dimensional
array" <shudder> <g>

I believe in the JavaScript Array being Dynamic, Sparse, Jagged and
now, and ever and forever!

:-D

P.S. Please, it is just a joke, not a call for discussion.

Surprisingly enough, I took it that way :)
