JavaScript JavaScript Loops, Arrays and Objects Tracking Multiple Items with Arrays Create a Two Dimensional Array

what is wronge?

Add three more arrays to the coordinates array. The coordinates array should have 4 arrays in it -- each of those arrays should have 2 items in it.

script.js
var coordinates = [
 ["hi", "bye"]
 ["fgh", "dfh"]
 ["fdgh", "fghd"]
 ["dfgh", "fgh"]
];

<body>
<script src="script.js"></script>

Hi Alexey,

I see there are some mistakes in double quotes "" and missing comma in each array.

Example:

var coordinates = [
 ['hi', 'bye'],
 ['fgh', 'dfh'],
 ['fdgh', 'fghd'],
 ['dfgh', 'fgh']
];

Dave McFarland's Javascript explained clearly, see 5:10 for Two-Dimensional Arrays concepts.

You are supposed to add values to the array you created in task one like below:

var coordinates = [ ['hi', 'bye']];

Make sure you are pushing values into your array coordinates.push( ['hi', 'bye'], ['fgh', 'dfh'], ['fdgh', 'fghd'], );
