What does useTransform and useTransition options from iScroll do?

Question

I have been searching for some time but can't find an answer to this question. In some forum entries some say it's better for performance to set useTransform: false and others true. The same goes to useTransition.

I have also read that setting -webkit-transform:translate3d(0,0,0); to the scrolled div helps it to go faster. But isn't useTransform option setting this css property?

Could someone please explain me what they do

1.useTransform 2.useTransition 3.-webkit-transform:translate3d(0,0,0)

and which of the options (true/false for 1 and 2, active/inactive for 3) is better for performance?

Thanks.

Answer 1

1. Difference between useTransition true/false
2. Problem with useTransform
3. Optimization using -webkit-transform

I'm not sure that useTransition:true really help you.
