Hi Jordan,

I have copied and pasted your code into task 3 and it let me pass the challenge... If it will not let you pass, delete the comma that follows the last array inside your main array. Please see code below for reference:

var coordinates = [
 [2, 3],
 [2, 12],
 [7, 10],
 [4, 5]  // Deleted the comma that followed this array
];

Hope this helps! Happy Coding!!!

Well normally it's complete valid code to let a comma at the end... Javascript don't mind normally. But syntactically speaking it's wrong.
