Can someone please explain to me of what use generics actually are and how they create faster code or improve the typing-workflow? I'm serious, I have no idea.

Googling it, I get:

> In a nutshell, generics enable types (classes and interfaces) to be parameters when defining classes, interfaces and methods. Much like the more familiar formal parameters used in method declarations, type parameters provide a way for you to re-use the same code with different inputs.

As someone who believes that OOP is bullshit and making things worse instead of better, can someone please put the above paragraph into humanly understandable words which translate into actual practical gains and improvements? Like ... actual use cases, maybe?

Thanks!
