Thank you Mario. The type parameters is the feature that I was waiting for just to start with Go.

Thanks man! Great introduction of the new version!

[@MarioCarrion]

Thanks Alex, take care!

[@JuniorMayhe]

Thanks for the good material Mario. Willing to see your take on workspaces. I have seen lots of confusing / hard to follow articles on that topic so far. Hopefully you can bring a hands on approach on this topic.

[@MarioCarrion]

Thanks Junior, yes I'll have something covering workspaces in the near future.

Thanks, man. Just starting out in Go. It is a great video.

[@MarioCarrion]

Thanks for watching. I'm glad this video was useful. Take care.

Hi! Thanks! The most comprehensive description of the new features. In other reviews they mention only about Generics. Also I saw in a review about the generics, the type "any". I am new to Golang... this mean that we can mix types in generics implementation?

[@MarioCarrion]

Hello! The type "any" is equivalent to the empty interface "interface{}" (it's literally an alias: pkg.go.dev/builtin#any); so literally any type in Go is "any"/"interface{}". Can we mix types in generics? Sort of, I mean the generic type can be used by "any" type, but when using that type itself we can not mix types, example: go.dev/play/p/-7L6Q9mckOJ

[@SirRFI]

@@MarioCarrion Can this "any" alias be used anywhere instead of interface{}?

[@MarioCarrion]

@@SirRFI Yes, go.dev/play/p/66l_l-3u_8H

[@SirRFI]

Any plans on making video about ValueObjects (objects that hold single value which has to meet certain criteria, like email address or one of values, enum like) concept in Go? And about immutability in Go? Because exported types can be created without constructor-like function with blank values, which kinda defeat the purpose.

[@MarioCarrion]

Yes I'm planning to do it part of the System Design series

[@codetoanbug]

thank for sharing.

What're you using to draw on your screen like that?

[@MarioCarrion]

It's called Presentify

Thank you! 👍🏼

Thanks for watching Phi! Take care

What Go needs is function parameter default values and struct member default values.

[@MarioCarrion]

I can see a lot of people benefiting from your suggestion, have you considered sending a proposal? github.com/golang/proposal

[@Elite7555]

And there are a thousand other things Go "desperately" needs. But what would Go look like if they were all realized?

[@smjure]

Mario could you please make a video on the new feature of go workspaces and its architecture in complex projects with local interdependencies as an option, of course simplified :) I'd love to see it how pro devs like you tackles it

[@MarioCarrion]

Hello, yes! That's another video I'm working on at the moment. Take care!

[@iRoNYwho]

Thank you.

[@MarioCarrion]

You're welcome! Best

[@Levelord92]

I think Homebrew is ready now with 1.18

[@MarioCarrion]

You're right! 🎉

[@SeaRich]

Benchmark generic?

[@MarioCarrion]

Would you mind elaborating a bit more?

[@Elite7555]

@@MarioCarrion, I think what they mean is how performant generic type parameters are compared to interfaces. But the Go team already said that performance most likely wouldn't be any better.
