I've researched the best animation libraries:
I've learned to use anime.js and creating the exact same animation as before was about 10x faster.
Other libraries I looked at:
Lottie
Framer Motion
Velocity. js
Popmotion
GreenSock JS
AniJS
Mo.js
Vivus.js
Vanilla-tilt.js
Typed.js
AOS
Bounce.js
KUTE.js
Scroll Reveal
Howler.js (for audio)
