I am having a heck of a time trying to figure out how to create a multidimensional array in jQuery.

I instantiate the array outside of the loop.

 <script>

 var myArray = [];

 </script>

Inside of my loop I want to add the array elements.

 i = 0

 [loop start]

      <script>

      myArray[i][$row[sku]] = $row[qty]; // sku might be repeated will this cause an issue? You will see in the error below 295518 is repeated...

      <script>

 [loop end]

In my source code it looks like this:

 <script>

 myArray[ 1 ][ 295518 ] = 122;

 </script>

Then I run this at the end outside the loop...

 <script>

 console.log( myArray );

 </script>

I get this error in the console:

Uncaught TypeError: Cannot set property '295518' of undefined 

Uncaught TypeError: Cannot set property '70252' of undefined 

Uncaught TypeError: Cannot set property '295518' of undefined 

What I am doing wrong in setting up this array? Thanks!
