Interfaces in the Go programming language are very simple but they are subtle.

I respect when the creator put so much effort to make the viewers understand the content by incuding real life example anyone can relate with, it becomes absolutely worth watching it rather than someone explaining from an abstract level. Thank you.

Calling it a protocol is a really neat idea and helped me understand it. When it came to interfaces the Tour of Go just brushed past it and went straight to exercises on readers and stringers, that even when I completed I still didn't understand the utility/power of interfaces. Thank you for your video!

Best video on Golang interfaces, and I watched every one on YT. I still have trouble with the concept (I come from other languages and didn’t do OO). If you ever revisit, maybe show how to convert a medium sized,working non-interface code over to Interfaces? Or something else… it’s both a simple concept and difficult to know when to apply it.

There are many tutorials on web with same examples of the interfaces for area of shapes, they were just copying from each others. This one makes sense. Well, that's say the interface is a method which calls all all the methods which has the same name from different types.

@base2446 2 жыл бұрын

This is interesting when coming from OOP languages. In C++ you'd create a "product" interface because the products also share title and price. But it seems that in Go interfaces are more granular. What would you do in the the case that you need to ensure a type has a "title", "price" and "print" method?

@danimunf 2 жыл бұрын

i'm curious about this as well

@dapodix Жыл бұрын

Interfaces in go deal with behaviours of types only. Srructs would be where you define what attributes your types take on (guitars, books, pencils) and you can nest srructs if that makes sense for your use case. By splitting the behaviours of types away - you get arguably better flexibility and with implicit matching, you simply add interfaces as you go to have existing types automatically take on new behaviours.

@inancgumus4125 Жыл бұрын

When declaring interfaces, restrict them to the behavior you want others to implement without considering the other types. Only consider what you need from the perspective of the package that needs that behaviour.

All this is good, but how do I access the fields of the concrete types when using interfaces? Let's say I have a book with a price on it and I have a game with a price on it. Within the loop call to x.Price is not available. Yes, I can implement both methods in a book and in a game with getPrice() and add it to the Printer, but 1 it wouldn't be a printer anymore 2 what If I don't want to do that?

@inancgumus4125 Жыл бұрын

Interfaces are about behavior rather than state. You should tell the types what to do without knowing how they do it. `getSomething` is not a behavior; it’s like poking into the internals of that type.

Why did you use pointers for the games?

@inancgumus4125 Жыл бұрын

It’s because the game type implements the print method with a pointer receiver.

@thachnnguyen 2 жыл бұрын

What type of programmers did you expect to address in this video? Why spent so much time explaining what an interface is at the same time throwing things like type list []*game (yes, a pointer to a game) but []book (no, no pointer to book) and glossing over the details? Worse, there's nothing revealing as your title suggests beside the normal polymorphism concept any tutorial already addresses.
