mistake in example code?

Hi,

In the "addToSet" and "removeFromSet" pasted below that appear after Exercise 14, shouldn't the double dots ".." be triple dots "..." in order to avoid requesting an element that does not exist?

addToSet = (set, values) ->
for i in [0..values.length]
set[values[i]] = true

removeFromSet = (set, values) ->
for i in [0..values.length]
delete set[values[i]]

It appears so.
