One way to think of a multi-dimensional array, is as an *array of arrays*. When you use brackets to access your array, the first set of bracket refers to the entries in the outer-most (the first level) array, and each additional pair of brackets refers to the next level of entries inside.

**Example**

var arr = [

[1,2,3],

[4,5,6],

[7,8,9],

[[10,11,12], 13, 14]

];

arr[3]; // equals [[10,11,12], 13, 14]

arr[3][0]; // equals [10,11,12]

arr[3][0][1]; // equals 11

Using bracket notation select an element from `myArray`

such that `myData`

is equal to `8`

.
