I hate them too. I have seen new typescript demos using it and I think it's stupid. I also don't like how some newer programming languages allows you to write implementation code in interfaces( looking at you kotlin ) . Interface should be used to only define structures. Implementations should be left to whatever implements it as the name suggests.
It's not standard, Hungarian notation was used back in the days when programming languages were very low level and IDE's were not a thing. It made a comeback these days because People wrongly assumed it was coding standard for android. Because people are more focused on coding than architectural understanding.

We're a place where coders share, stay up-to-date and grow their careers.
The i' infront of interface names some people add.
WHY. JEBUS. BRIST...just!... no!.. please?
I didn't know this was a bad thing! I was taught it in college a couple of years back when we covered design patterns...

Exactly, everyone think it’s the standard.
But very few really know why. :)
The i’ is not needed because you are denoting a subject type, like horse.
The actual class implementing class will always be a subtype with a more specific name like FastHorse, or IcelandicLeperHorse or some such.
If we actually had a horse’ class, then we would not really need a horse interface, because we would not have subtypes.
This makes the i’ entirely redundant, since interfaces serve like a type, similar to how variables and classes do.
I mean you would not prepend a number variable with n’ would you?
Counter argument here would be that sometimes knowing the structure type is practical, like if you are using inflection.
But inflection is bad, and again it’s a specific usecase. So making it a global rule’ is kinda overkill.
I have seen that argument somewhere before, but i still wonder.
Would the class definition not suffice as the type?
I mean dependency injection systems usually just manage shared instances.
Maybe it's language dependent and i am just missing a piece of the puzzle. :/
