If there are several components, for example, several counters on a page, the disadvantage is that several components will refer to one variable. In the case of useRef, each component will have its own instance of this variable.

Yes, that's the case, Valerii. When component has a few instances some problems can occur. But when we use this approach in a single-instance component like page view for example, everything should be fine.

Is there any downside to doing it this way? Looks clean :)
I use this regularly and I've never faced problems. :) I treat this a little like a "class property in functional components".
But of course there are cases where this approach can not work properly. It's depend from an individual case.

That's true ! 🤔 So storing it outside the component can actually be quite dangerous.
Thank you for that ! :)
