Just is case somebody had the same question:
After 8hs of learning webworkers, I can say yes, works, perfect, the main thread now is light really light and the animation performance is 100x times better, GSAP is insane because from the worker I import my functions and execute all the animations in different threads, all is working perfect but its not working on iphone, for some reason, but the iphones run the old version of my animation (pure gsap and svg) perfectly fine.
Thanks, this forum is amazing
