Interfaces in Go are SO GOOD - Go / Golang Interface Tutorial

Despite not having Object Oriented Programming language features, Go does still have interfaces.

Interfaces allow you to interchange what data types you are passing as arguments to a function, as long as that type has the required methods.

Interfaces in Go are different compared to, say, C# or Java, in that you don't have to explicitly state you are implementing an interface, which is pretty cool.

I was taking "a tour of go" and got tripped up a lil bit. this was the first video and you cleared it right up for me. thanks brother, I appreciate you ☮🙏🏽

Been using your series to get up to speed with Go. You've got a great teaching style, It's a lot easier to stay engaged with a lesson that feels more like an authentic interaction and less like a formal lesson in a lecture hall.

[MeeGrimlock]

Thank you; I've gone through a lot of content describing/demonstrating interfaces but yours is the most concise and clear

[gaurangpatel]

Thanks for the explanation Man!
This is gonna save a lot of confusion for me! 💯

[MDMonirulIslam-plyu]

Very nice and clear! thank you so much!

[JonBrookes]

deffinitely the most concise and clear ( as J said ) - thanks for this very good explanation. The aspect of 're-use' could be another video ? say not just reuse of the io package but reuse of the 'printer faxer scanner' mebe ? also this has application in the area of testing - ie 'mocking' a back end, a db for example - I can see it has many uses, thanks again for this eye opener - you explain this very well indeed !

[anarrzayev]

simple and practical explanation, great job!

[nikowahyufitrianto]

thank youu, great explanation. well done

[artemcodes]

Thank you for the video, I found it really useful.
I have one question, you mentioned that it's great that go has implicit interfaces, rather than explicit. I can't come up with an example where it could be better. It would be cool if you can explain or send a link where I can read about it. Thanks :)

[ZachPeters]

I've been loving your go videos man. Got any more planned?

[ultiumlabs]

got new insight how to implement interface in Go, thanks

[farhanyousaf]

Awesome stuff. What font and prompt do you use? Assume it’s zsh.

[haxidenti]

what a good font. Where i can get that?

[AntonyMapfumo]

Clearly explained, thanks. By the way what font are you using?

I am here to learn more about the interface, but it is excellent to know Go allows the same name methods with the different receivers.

[medhathelmy]

Hi! If both the structs should have the same printing method (we need only one print method for all structs), How we can do that? (the receiver should accept all the structs) .

[ashtwenty]

Idk man. A printer should only be able to just print. Ie return string err, Could just be a return error for trying to fax on a printer. The if err! = nil then...

[shivah]

I feel you should put down a design before getting into code. I watched the video twice to understand what you were trying to achieve. second thing, impacting content is lesser, can be finished in 12-15 mins.
