GSAP
Think of GSAP as the Swiss Army Knife of javascript animation...but better. It animates anything JavaScript can touch (CSS properties, canvas library objects, SVG, React (JS), Vue, Angular, generic objects, whatever) and it solves countless browser inconsistencies, all with blazing speed (up to 20x faster than jQuery), including automatic GPU-acceleration of transforms.

GSAP は場合によっては有償ライセンスとなるので、不安な場合は Tween24.js を使うのが良いかも
