No, they're not obsolete. What did you try?

There's an example here:
https://developer.mozilla.org/en/Core_JavaScript_1.5_Reference/Objects/String/t
oLowerCase

It's the default value of the string (e.g. when used with the K_EDIT mode
flag).

Actually, unless you're using K_EDIT, you don't need to specify the string at
all. The method implementation is smart enough to know the difference between
numbers (e.g. maxlen and mode arguments) and string arguments. Many of the
Synchronet JS methods are this way.
