Heterogeneous arrays

Now that we've reviewed some array basics, it's time to cover a little new ground.

First, it's not necessary for you to put the same type of data in an array! For instance, you don't have to have

varpronouns = ["I","you","we"];varnumbers = [1,2,3];

You can have a heterogeneous array,which means a mixture of data types, like so:

varmix = [42,true,"towel"];
