What are mixins used in react for (I don’t quite understand what they are at all, could you explain in a nutshell?) and what is the alternative for them? It seems like they are no longer in classes, so what is used in classes instead of mixins then?

A mixin is an impurity.
For example, if you had a "coffee" component, you added the "milk" mixin to it - you got "coffee with milk".
And if you add mixin "milk" and boil it (or whatever the process is going on) - you get a cappuccino.
That is, you have achieved similar effects for two different coffees (components, types) using the same type of mixin (milk). The example may not be the best, but I think it's understandable. A mixin is a set of additional logic.
What's in classes instead of mixins? Think HOC (Higher Order Component)
