Javascript - Removing all side effects from an external script

Is it possible to remove all side effects created from a third party script, without concretely knowing what they are?

Simple toy example:

A script is loaded via a script tag, it created a new DOM element, and also attaches some data to the window object.

My application now wants to remove anything this script has created/added to the browser.

Is it possible to delete all the effects?

No, it's not possible. The only way to «remove» all effects from a external script is not loading it in the first place. Even if you target all script elements and delete them, the code would have already been executed.
