Expo

Eases in a strong fashion either at the beginning (easeIn), the end (easeOut), or both (easeInOut). Expo is a convenience class that congregates the 3 types of Expo eases (ExpoIn, ExpoOut, and ExpoInOut) as static properties so that they can be referenced using the standard synatax, like Expo.easeIn, Expo.easeOut, and Expo.easeInOut.

Properties

easeIn : ExpoIn

[static] Eases in a strong fashion starting out slowly and then accelerating.

easeInOut : ExpoInOut

[static] Eases out in a strong fashion starting out fast and then decelerating.

easeOut : ExpoOut

[static] Eases out in a strong fashion starting out fast and then decelerating.

“ After searching around the web for alternatives, I found GreenSock to be the most performant. ”

Lamin Sanneh

“ Really quite impressed with @GreenSock JS - even the small things. ”

Joseph Labrecque, ‏@JosephLabrecque

“ Aside from GreenSock’s laser-focused attention to detail, GSAP is fast, reliable, flexible, exceptional value (read: free in most cases) and, very importantly, supported. ”

Chris Gannon

“ Go and browse through FWA or Awwwards, then view source of anything you see that has cool animation and you will be surprised how widely GSAP is used. ”

John Polacek

“ It's shocking the @w3c didn't use @greensock as a model of how to do animation via code. Did they even ask animators what they use? ”

Elliot Geno, @ElliotGeno

“ The best thing about GSAP is that it just works, and it works well. On every single browser I’ve tested. ”

Chrysto Dimchev

“ GSAP and CSS Transitions: I've done both, and its like comparing an F16 to a horse. Take like 10 minutes to try. ”

Vic C., @puppetMaster3

“ GSAP was a revelation for me to be compared with the introduction of jQuery ”

Jan Paepke, @janpaepke

“ @greensock is just pure awesomeness. What more can be said? ”
