How can I tell if too much javascript is hurting the site`s navigability?

I`m working with a Drupal site that has a slider on the homepage. This slider disappears when I turn off Javascript in Chrome. Additionally a dropdown menu lower down on the page becomes unclickable when JS is turned off. How can I tell if this is hurting the site`s navigability?

W.E. Jonk: To be honest it is impossible to know for sure if this is hurting your ranking. However in general one can say that navigation does not hurt your ranking....

That is, google can execute javascript and when you use things that all over the the internet it won't really hurt your ranking. ;
Tino Triste: As a rule of thumb if JS menus, tabs, sliders, etc aren't visible with JS turned off. They're not seo friendly, I would find another script.
Shawn Cohen: Oddly enough, the main navbar isn't JS but the slider bar and a secondary dropdown menu is. I think we'll leave it for now since the linked pages are ranking--but thanks for your help!
Tino Triste: Ok good luck with it all +Shawn Cohen
Shawn Cohen: Thanks!
