How do I add an array inside of a two-dimensional array? Do I use the push method?

  ['cheese','boss', 'elephant'],
  ['monkey', 'search']
];

coordinates.push(["x", "y", "z"]);

al76 no need to use the push method for this coding challenge.

You've already added two arrays to your coordinates array, just add two more.

Just like that - using push method BUT where does your first array ends? Do you mean this:

var coordinates = [
  ['cheese','boss', 'elephant'],
  ['monkey', 'search']

];

If you use push on this I think you get a cube - a three dimensional array. what is that you want to do?

It doesn't work with the code I have given in the exercise above?

It works it pushes the new array but it throws undefined for the first one. Try it in the console
