I have a difficult time believing that there is any utility in a confetti animation library when that confetti is shown over a page in a web browser.

What could the utility of showing confetti over a webpage possibly be?

Same utility as animations in general. Such animation as this one for example fits when a user receives something or solves a challenge and similar

Those don’t have utility, either.

I don’t know why web devs feel like they need to tell users when they’ve succeeded at something like clicking a button.

People understand when they’ve accomplished something. We don’t need rituals around this, even simple ones like this.
