JavaScript has 1-dimensional arrays, but arrays are first class objects, so you can nest them to get something analogous to a "multidimensional" array

<http://www.ecma-international.org/ecma-262/5.1/#sec-15.4>

You'll probably want to stay under 2^32-1 for each level of the array. Individual implementations may have one-off errors at this range.

You can represent tree structures with arrays, yes.

JavaScript arrays can be sparse.
