Nice video!
One comment though. It is just my opinion though. For getting the input in golang, I most often use the bufio scanners. But as a beginner I found the fmt.Scan methods to be much more intuitive and having less syntax around it. So you don't have to take it, but my advice is when doing another beginner tutorial like this, and the focus is not on getting input, you could use the fmt.Scan method to make it more easy to follow.

That said, I think these methods require pointers so it really is just preference

Not a big fan of Go but I do enjoy the ideas you present. Nice vid my dude!

Thank you for your awesome videos!
I'll write Master thesis about the possible fields of application for predictive analysis in the controlling departments of companies. Thanks to your really well explained videos im fairly convinced that I'll be able to add a chapter about an own analysis.

Hi Tim, nice tutorial. I like the way you explain. This session was a bit hard to understand. So there seems to be several ways to scan from console input as comments shown. Could you give some more examples with pros and cons? Regards Andreas

Thanks, Please give us as much as you can with Golang. I can't wait for List, maps, func.... Thanks

Could also use bufio.NewReader() and fmt.Scan() then read from os.Stdin.

keep going bro keep going
thanks for this tutorial

Hey Tim, are you using the golang extension in vscode? If yes, please tell me how did you disable format on save for go. I checked the vscode as well as the golang extension settings and tried disabling the "lint on save" and "build on save" options but with no luck :/

[openjaws]

Nice video bro, maybe I'll look into golang

[xsendilien]

What extensions do you use in vscode for golang? Im new in vscode.

Hey time, can you just prepare a cheat sheet for GoLang, it would be really helpfull.

[edtix]

I suppose you use word "object" to be more intuitive but what exactly is "scanner" variable?

[Sergey_Latyshev]

When I watched this video last year, I thought: what a stupid language that has so difficult implementation of such a simple task like input. But recently I returned to Go by another, better tutorial and learnt that there is a simple method 'fmt.Scanln (&variable_name)'.

Has the give away winner been chosen ?

Hi bro! And how to make the function write the number for each digit into the map? For example, input: 12334. Output: 1: 1; 2: 1; 3: 2; 4: 1. On Golang

i want asking to you. How about atribut strconv.ParseInt can be defined with result 10 and 64. What is that ASCII in your mind?

[engageintellect]

Why not just do something like:
var year_born int
fmt.Print(“what year were your born: “)
fmt.Scan(&year_born)
result := 2020 - year_born
fmt.Println(result)


The whole scanner thing just seems extra, or did I miss something?

[mohammadhonarvar]

Do you have any tutorial for go fiber framework?!

[umangagrawal]

Hi Tim, I had one doubt
When I run fmt.Println(*os.Stdin) it prints a memory address like this {0xc000182000}
What does it signify and how does it work?

[aayamshrestha]

What is different between bufio and fmt.Scanln ?
