Is it obvious to everybody that:

var myArray = [3,4,5] 
for (j in myArray) { 
  $.writeln(j); 
}

produces in the JavaScript Console:

0
1
2
Execution finished.

I stumbled on a script yesterday that I wrote a while back that used this technique for iterating through an array but I had to step back and try this test to convince myself that it actually works.
