Sounds like you agree here.

Sounds like you agree here too?

You aren't actually answering Boris question, but rather point out a
grammatical error in the question. So let me repeat the question with
the grammatical error fixed. Please do excuse any other grammar errors I
introduce as English is a second language to me.

3)  The behavior of the function when null is passed as value for an
     argument is almost always either that of "" or that of "null".
     Which one depends on the exact DOM method.

Do you agree with this?
