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

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.

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

Hey Ja'Nel,

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

var coordinates= [ [], [] ];

Thank you!

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

Awesomesauce! =] It is definitely a great resource!
