const animazeOpacity = () => animaze({
    tick: v => { myDiv.style.opacity = v; }, // v is varied from 0 to 1
                                             // during animation
});

const animazeScroll = () =>  animaze({
    tick: v => window.scrollTo(0, 200 * v),
    duration: 500, // default is 240
    ease: k => 0.5 * (1 - Math.cos(Math.PI * k)), // this is default one
});

animazeOpacity().then(animazeScroll); // animaze returns Promise
