Converter jQuery--->JavaScript statements?

Converter jQuery--->JavaScript statements?

As far as I know jQuery is completely based upon JavaScript.

So assume I am not allowed (or because of other reasons) to use jQuery on a particular web page and have to code something in pure JavaScript.

Currently I have the jQuery statement(s) and need the corresponding JavaScript statements.
Ok, one jQuery statement could result in 30 to 40 JavaScript statements but this shouldn't count as long as the pure Javascript show the same result.

Is there a converter jQuery statement---->JavaScript statements?

Thank you
Peter
