Looking to learn something new?
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.
var coordinates = ;
An array literal is just two brackets like this "", so try setting your new variable
coordinates equal to those two brackets. :)
var coordinates= [ ,  ];
I ended up figuring it out. MDN was very helpful.
