TweenMax builds on top of TweenLite and TweenLite’s “big brother”, TweenFilterLite, to round out the tweening family with popular (though not essential) features like bezier tweening, pause/resume capabilities, easier sequencing, hex color tweening, and lots more. TweenMax uses the same easy-to-learn syntax as its siblings.

In fact, since it extends them, TweenMax can do anything TweenLite and/or TweenFilterLite can do, plus more. So why build 3 classes instead of one? Good question. The goal was to maximize efficiency and minimize file size. Frankly, TweenLite is probably all most developers will need for 90% of their projects, and it only takes up 3k. It’s extremely efficient and compact considering its features.
