I tried copying and pasting isObsevableProp into my code after getting this message, but the function doesn't exist! Then I noticed the typo. It should be: isObservableProp

Also the docs need to be updated. They still say isObservable will take a 2nd arg.

Hi @mnpenner,
thanks for the effort!

Are you willing to submit a PR?
I can help with anything related to PR submission, if you are new to it.
