For folks that want a written version the TL;DW:

<button onClick={() => window.scrollTo({ top: 0, behavior: "smooth" })}>
    Go to top
</button>
Enter fullscreen mode Exit fullscreen mode

You could track the scroll position of the window with the scroll event on a useEffect (which you should debounce). And you could also change that hardcoded 0 to whatever value makes sense for your app.

Cheers!

Sweet, thanks for that input! I've been looking into browser performance best practices but I'm still trying to get better at the basics of react! I'll look into this though πŸ’―
