A modern programming language that makes developers happier.

kotlinlang

we decide to not use any of theses, we just name an interface as MyStuffInterface, then used it in the implementation.
Tks for inputs ;D

Seems like the worst of both worlds. Either you think the fact it's an interface should not be exposed in its name, so call it `MyStuff`, or you don't, in which case `IMyStuff` is arguably more concise and allows you to call the implementation just `MyStuff`

I like the `I` convention myself: when I review code, being able to see right away that something is an interface is valuable.
