Does not use passive listeners to improve scrolling performance  en

Hi there,

Google PageSpped show me "Does not use passive listeners to improve scrolling performance"

As I read need to add the following code 

jQuery.event.special.touchstart = {

        setup: function( _, ns, handle ){

            this.addEventListener("touchstart", handle, { passive: true });

        }

    };

right after jQuery load.

Is that correct?

If yes I have to edit jquery and put that code at the end of the existing code? If not, where and how I can use it? 

I'm sorry for my continued questions I have as a hobby on my webpage and my best friend websites, and always I try to improve it. 

I'm not a programmer I'm just Mechanical/ Electrical Engineering / Naval Architecture with zero knowledge of code....

Regards,

Nek/Greg
