New to Go Programming — Looking for Guidance

[Kaushal Shriyan]

Hi All,

I am new to the Go programming language and have no prior programming experience.

I would appreciate your guidance and suggestions on how to get started. I am very eager to learn and plan to dedicate time every day to understand it better. I look forward to your advice and recommendations.

Thank you in advance for your support.

Best regards,

Kaushal

Hello,

I have here some links as starting point that have been used by me some time ago.

https://go.dev/tour/welcome/1

https://go.dev/doc/tutorial/

https://www.w3schools.com/go/index.php

https://gobyexample.com/

Then in  Go playground one can practice writing smaller Go programs

Go is pretty sophisticated for a first language (it is a sharp knife; a professional level tool), 

since it assumes you understand the computer underneath. I'm not saying its a bad 

choice as a first language, I love it, but you are jumping into the deep end pretty quickly.

If it really is your first language, you probably do not have a computer

science coursework background. I would recommend then, if that is

the case, reviewing a sophomore level text on computer architecture, like Hennessy and Patterson's 

classic Computer Architecture: A Quantitative Approach,

just so you have a mental model for the machine. Having such a model is essential,

and the Go language teaching materials will all assume you already possess one

as a pre-requisite.

correction -- it was a different book title by the same authors that we used in sophomore level

computer architecture class:

"Computer Organization and Design: The Hardware/Software Interface"

https://www.amazon.com/Computer-Organization-Design-Interface-Architecture/dp/0123744938

The first book I cited is a fine book by the same authors, but it is pitched at CS graduate 

students rather than undergrads taking up the study of computer science

seriously for the first time.

Thanks, Roland and Jason, for the guidance. I really appreciate it. I will get started, and I will reach out here if I have any difficulty understanding the topics.

@Jason — Are you referring to https://amzn.in/d/84lvFPD? Please advise me.

Best regards,

Kaushal

Yes, that's the one.

Hi,

in case you are in interest of the design patterns applied to Go.

>>I  provide links here to educational resources.

>>GitHub - AlexanderGrom/go-patterns: Design patterns in Golang (in russian)

>>Go Patterns · GitBook (tmrts.com)

>>GitHub - PacktPublishing/Go-Design-Patterns-for-Real-World-Projects: Go: Design Patterns for Real-World Projects, by Packt

>>Patrones de Diseño en Go (designpatternsingo.com) (in spanish)

But I would like to stress one thing.

Due to absence in GO dynamic dispatching some of the patterns must be implemented, say as they must be in GO. :-)

Thank you.

Not sure what you mean? Method calls on interface values are dynamic dispatching.

Hi, Brain.

the sample is there:  Go Playground - The Go Programming Language

Sorry, of course, Brian not Brain.

I do apologize. Sorry.

Dear Alex (alex-coder), 

Here is an easy rule to remember. There is one, and only one, 

way to get dynamic dispatch in Go. That is: calling through an interface.

Your example is using embedding, not calling through an interface, so it is not relevant to

how dynamic dispatch works. 

You have guessed that Go works like other languages,

and unfortunately your guess was wrong, and this has led you to the wrong conclusion.

Embedding will automatically generate methods from the embedded type on the

outer type, but it will not give dynamic dispatch. 

As above, the rule to remember is that _only_ calling-through-an-interface variable gives 

dynamic dispatch in Go.

A simple demonstration:

https://go.dev/play/p/WzhwvLB9VEY

Now that is understood, my recommendation is that you should 

usually still avoid interfaces for as long as possible, until you

absolutely must deploy them, because interfaces 

make it harder to debug your program, and can be slower.

best wishes,

Jason
