Arrays are one-dimensional; that means they store only one row of data. But you can make an array multi-dimensional by putting arrays inside arrays! Like so:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var arr = [["Two-dimensional", 2], ["Two rows", 12]];
|
||
|
|
```
|
||
|
|
|
||
|
|
The above array has two dimensions.
