Help with two-dimensional arrays

I was working on the coding challenge 'Create a two-dimensional array' when I ran into some trouble. I had had already completed tasks 1 and 2 out of 3, but I couldn't manage to pass Task 3. Here is my code:

var coordinates = [
 [2, 3]
 [2, 12]
 [7, 10]
 [4, 5]
];

It says 'Oops! It looks like Task 1 is no longer passing.' Here are the tasks:

  • Task 1 - 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.
  • Task 2 - A two-dimensional Array is an array of arrays. Add 1 array to the coordinates array. That new array should have two items in it.
  • Task 3 - 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.

Please help, Thank you.

Looks like your only problem is that you forgot to put commas between each array

var coordinates = [ [1,2], [2,3], [3,4], [9,10] ];

solution:

script.js 
var coordinates = [
 [2, 3],
 [2, 12],
 [7, 10]
];

You forgot to add the commas after each of your arrays

EX: var coordinates = [ [2,3], [4,9], [6,8] ];
