A two-dimensional array is an array of objects. I answered True but that's the wrong answer. Why?
Arrays ARE objects. The typeof operator when applied to an array will return "object". I found this information on the W3 Schools website, http://www.w3schools.com/js/js_arrays.asp
Can anyone clarify? Thanks so much.

The question asks: "A two-dimensional array is an array of objects.", which is false.
- An array is a list of objects.
- A 2D array is a grid of objects, or an array of arrays of objects.
- A 3D array is a box of objects, or an array of arrays of arrays of objects.
