I have been developing applications in JS since its early stages but i never had worked so much about animations till then until using green sock apllication! The best thing was when we integrated this into our existing platform everything just changed around after few days people were really surprised because nothing else has improved like what they achieved through greensocks! If anybody wants his or her application develope more interactive try putting Greensockets js at least once if not twice before starting any development process otherwise user experience may decrease. !! It's a good tool for development, it's very fast and it's easy to use.It's possible to do all kinds of animations, from simple to complex. It's very flexible and it has a powerful library. There are many ways to do the same thing, and that's why it's hard to choose a good tool. I recommend you to use it. It's a very good tool for development. I've been using it for a while and I have no problem at all. I think that it's a great tool.
