Can you tell me anything about FastDOM and if GSAP uses something similar or if you have ever heard of it, etc?  I personally haven't heard anything about it until recently when someone recommended it to prevent some layout thrashing (something you see commonly with parallax animation where you are trying to move something based on scroll position, etc, etc).   Whatever it is doing or whatever it does, it seems to boost performance.  Do you know anything more about the techniques it uses and does GSAP do something similar? different? better?  or are there some drawbacks to the process that FastDOM is using? etc.

Nope, never heard of fastdom, but it seems it is just handling the batching of read and write operations to avoid layout thrashing.

GSAP has been implementing this technique since version 1.12.0.


You can read a bit about it here: https://greensock.com/gsap-1-12-0


Thanks for asking!

thanks Carl!  I figured we were doing something similar because of the rock solid smooth performance, guess that is why i never needed another tool ;)
