JavaScript JavaScript Loops, Arrays and Objects Tracking Data Using Objects Review Loops, Arrays, and Objects

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.
