Subject: Showing part of an array....


Let's say you have an array which might contain:

colors = ["black","white","red","yellow","green"]

And you'd like to see the first three elements with a ... attached to 
the end if there are more than 3.

"colors[0,2].join(', ') + ' ...' if colors.count > 3"

Which of course is blank in there are less than 3 elements in the array.

How do I limit the if to only working on the ' ...' part?

Sorry for the newbie question, but I have no idea what to even look for 
in the docs.

Thanks!
