Tween

Eases between 0 and 1 over a duration. You manually call step() to advance the tween in your custom event loop:

import { Tween } from 'oblik/utils/tween'
import { easeOutExpo } from 'oblik/utils/easings'

let tween = new Tween(1000, easeOutExpo)

tween.on('update', value => {
    console.log('value', value)
})

setInterval(() => {
    tween.step()
}, 200)
