GSAP – A wildly robust JavaScript animation library built for professionals [https://gsap.com]

I keep hearing about it, but I've never used it. Why would I use it over https://animejs.com ?

[ZachSaucier]

GSAP is a bit more robust than anime.js. Over the years anime has been adding more functionality and changing its syntax to be more like GSAP's. They're both solid libraries though

I only discovered GSAP the other week, very quickly solved a complex animation problem and walked away quite impressed.

Now I'm looking at AnimeJS and my mind is properly blown, looks even better.
