How to export a JavaScript function that gets the results from an eventListenerClick?

I have a javascript file where I let the user set some values as an exported function looks something like this setValues(1,'test'). In this set call I set an eventlistener on a button to call a function document.querySelector('#spinner').addEventListener('click', spin); this calls the function spin(). I would like to get the results back from this and have the user be able to call getResults() and the user would be able to view the results from spin().

I am aiming to export both setValues() and getResults() so the user can import the module and use the functions. How can I get it so getResults will properly show the user the values?
