Similar to one-dimensional arrays, you access the data in multi-
dimensional arrays in much the same way you assign data to multi-
dimensional arrays.

Accessing Data in a Two-Dimensional Array

Ready to create an array of stir-fry ingredients? Okay, here we go.

...

The array has been created and populated.
Now, let's access
the data.

This program prints all the elements of a two-dimensional array by
going through them with a while loop. Here's the code:

while (Count<=4)

{

document.write("

" + StirFry[Count][0] + ", which
is/are " + StirFry
[Count][1] + " in color.")

Count++

}

Access each of the elements in the two-dimensional array by a statement
like StirFry[Count][0]. Count is the element of StirFry
that's
relevant, while 0 or 1 is the number of the needed element in the array
that fills the Count space in StirFry.

You may find it helpful to think of Array[n][p]
references in terms of
coordinates: The first number is the "down" coordinate, while the
second coordinate is the "across" coordinate.
