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

Posted by Ja'Nel Johnson

What is this asking me to do?

In this code challenge you need to create a two-dimensional array -- an array of arrays. Start by creating an empty array literal named coordinates.

I've typed in several things. Seems simple, but I'm not getting it.

Please help.

script.js 
var coordinates = ;
index.html 
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>JavaScript Objects</title>
</head>
<body>
<script src="script.js"></script>
</body>
</html>

Hey Ja'Nel,

An array literal is just two brackets like this "[]", so try setting your new variable coordinates equal to those two brackets. :)

I ended up figuring it out. MDN was very helpful.
