Is calling .destory() necessary?

[michaeladamkatz]

When I call let mySwiper = new Swiper( myContainer, ... ), my understanding is that swiperjs adds a bunch to the DOM inside myContainer, and I get back a swiper object, which I store in some variable or data structure.

I'm trying to understand if I need to call mySwiper.destory() when I'm done with it, or if it's enough to empty the myContainer DOM div and give up the reference to the swiper object, like with mySwiper = null.

I looked at the code for destroy() and saw a lot of removal of event handlers and such, but by removing the contents of myContainer from the DOM and giving up my reference to the swiper objects, doesn't it all get cleaned up through garbage collection anyway?
