Built-in eases
Both the js and waapi animate() functions include a collection of built-in easing functions that can be specified by name directly in the ease parameter:
animate(target, { x: 100, ease: 'outQuad' });
animate(target, { x: 100, ease: 'outExpo' });
animate(target, { x: 100, ease: 'outElastic(.8, 1.2)' });
All built-in easing functions are also accessible through the imported eases object:
import { eases } from 'animejs';
eases.outQuad;
eases.outExpo;
eases.outElastic(.8, 1.2);
