hi guys,


i have a slider where i build timelines based on the dynamic changes of the content and user actions.  

It can happen that the same timeline is not used any more, but it can happen that it reused later. 


However if the slider runs over a while, it can logically have a row of timelines defined somewhere in the memory.  I define timelines within a function locally, and give it for other local functions  to starting / stopping it on demand.  Once that happen, i lose focus of it.


The question basically if i should tidy up these timelines, or will it after the tweening just disappear after a while, freeing the resources ?


If not, how should i make sure that not unneeded resources are in use later ?

In general, no, you don't need to worry about GC with GSAP. It automatically does stuff under the hood to release things when appropriate. However, you should still use normal good practices, like don't maintain references to objects that you don't need anymore, which could be tweens or timelines or elements or whatever. GSAP cannot protect you from writing code that GC-proofs objects but the system itself handles its own GC management well.  


Definitely make sure you're using the latest version of GSAP, though. That's pretty much always a good idea. :)
