OP solved it, closing

I'm having the same issue. Only case that doesn't work is the main test for NaN. Strings that evaluate to numbers work. How can I fix this??
EDIT - figured it out! Phew, sorry for the panic :P. Had fun on this one!

Could you elaborate what errors you're getting and what it means that 'NaN test does not respond successfully' ? How would anyone fix such vague issue?

Maybe you're checking for NaN incorectly, or my guess is that you're throwing an error for non-NaNs. By looking at the tests, I think there's only 1 NaN test.

Thanks, approved!

plz, see above

RTFM:

Second argument (optional): space-delimited list of minor words that must always be lowercase except for the first word in the string. The JavaScript/CoffeeScript tests will pass undefined when this argument is unused.

You put too many information into stdout.

You're welcome.

You have great opportunity to learn from all the assistance you're getting!

No it isn't a function.

txt is like position an object member.

It's a abbrevation for text ;-)
