10,452 PointsTwo Dimensional Array Challenge Help
Hi All,
I am a little stuck on the coding challenge for this video
The task is:
A two-dimensional Array is an array of arrays. Add 1 array to the coordinates array. That new array should have two items in it.
I've tried various ways of amending my array but no luck. Am i doing something wrong?
My latest code is as follows.
var coordinates = new Array()
coordinates[ [0, 'test']
];
However this flags up with the error:
Bummer! There should be one item in the coordinates array.
Any help would be appreciated. Thanks

27,008 PointsA variable can contain an array when it's declared, but the way to do it is to use the []. So for coordinates, you would say
var coordinates = [];
That creates an empty array. You can then add arrays into with a method like push. So you can type something like
coordinates.push(['north', 'west']);
So then coordinates is an array which contains a single array of ['north', 'west'] .
[['north', 'west']]
You can continuously push arrays into the coordinates variable and they will be independent arrays contained in the parent array.
