--- title: Access Multi-Dimensional Arrays With Indexes --- ## Access Multi-Dimensional Arrays With Indexes Consider the following multi-dimensional array: ```javascript var arr = [[1, 2, 3], [4, 5, 6], [7, 8, 9], [10, 11, 12]]; ``` This is what it looks like in tabular form. | Position | 0 | 1 | 2 | 3 | | --- |---|---|---|---| | **0** | 1 | 4 | 7 | 10| | **1** | 2 | 5 | 8 | 11| | **2** | 3 | 6 | 9 | 12| Now all you have to do, is choose the coordinates of the data you desire! For examples, if we want `myNum` to equal 8, then... ```javascript var myNum = arr[2][1]; // Equal to 8 ``` Or, if you want it to equal 1. You do... ```javascript var myNum = arr[0][0]; // Equal to 1 ``` You first start off by choosing what column the number is in, then you choose the row. It's kind of like the x-y coordinate plane!
