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

I don't understand why its not going through on Challenge Task 3 of 3. Anyone to help me?

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 = [];
coordinates.push(['north', 'west']);
var coordinates = [ [2,3], [3,1], [4,6], [5,10] ];
index.html 
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>JavaScript Objects</title>
</head>
<body>
<script src="script.js"></script>
</body>
</html>

You could just solve this with a literal like you have on the last line, but then you wouldn't use the other lines (and you should never declare a variable more than once).

But since you solved step 2 by pushing an array into the empty one, you could also just push 3 more:

var coordinates = [];
coordinates.push(['north', 'west']);
coordinates.push([2,3], [3,1], [4,6]);
