Golang Tutorial : Go Full Course

I wrote a Techno-Thriller called Whispers if you're interested: amzn.to/4cfdtNW
I'd greatly appreciate a review for it if you have time.
I created this Golang tutorial to be the definitive course. I provide in this full course more information than you can get in any book. The table of contents follows below. Both the core language and numerous projects are provided to help you master Go. Also there is only one 5 second ad, so nothing will get in the way of your learning process!
Go is one of the fastest growing languages and for good reason. Go makes it very easy to write fast code without having to tweak with the code. The code is understandable, efficient, excels at concurrency, provides great backend support for web apps, handles errors much like Rust and manages memory efficiently.

The legend. Man its its been awhile. I recently got interested in Go because I wrote a small program in it to download some images (fed the command line args to go from python) and here you are with a 4 hour video on the language. Your hands down the absolute best when it comes to needing to get up in running in a new language or framework and don't need 3 hours of videos of basic programming concepts rexplained to you.

[@derekbanas]

Thank you for the nice compliment :) I'm very happy you enjoy my videos.

[@godfather00cz]

finally! the Go-lang gopher made it to the Derek's show, thanks!

[@derekbanas]

I hope you find it useful :)

[@theederominus]

@@derekbanas hey Derek , is this video still useful to get started to knowing some code and to get involved to learning to make projects rather than “cheating myself and copying code”? I’ve been looking everywhere, got anything I can contact you on?

[@rajaths697]

You are my go-to person to learn anything programming wise. Crisp and clear explanation and the best part is I don't nod off while watching your videos because every single sentence teaches me something new and the pace is just perfect for someone like me who would want to learn things fast. Keep doing what you are doing man! Fantastic. Also wanted to know if you would consider making tutorials about kubernetes, cloud tech and stuff like that

[@pablopelaezgallego4806]

Amazing course! Helped me a lot to clarify some language stuff. Maybe, on the channels sections needed to check another resources on internet to understand its purpose, but overall you covered all the necessary concepts to start working on Golang. Thank you so much!

[@Telepriester]

Hey Derek, great video (as always) thank you so much for it! Since you cover so many different programming languages in your videos I would be interested to know about your technique to learn these different languages so well in such a small amount of time. :)

[@samk4186]

Great tutorial. I enjoyed it and practiced while watching..

[@AlexGelinas42069]

If anyone is wondering why imported modules were occasionally disappearing for Derek (esp noticeable during the html segment) that's because when Golang is integrated with your IDE (VS Code in this case, goland, etc) then when you save the file it does some pre-compiling for you, along with some linting (hence why he would save and it would change some positioning). Another thing this precompiler does upon saving is removing unused modules. However, it's not all about deletion, it also adds ones you might want if you call a module but haven't yet added it via imports. For example, if you are in a completely fresh file with and you put fmt.Println() into a function and save, it'll add the "fmt" import for you. It's very convenient and means you don't really have to think about that part of the file(s) at all =]

@Derek Banas Thanks for the great tutorial, 9/10 I liked the pace, and there's a good balance of touching on all the important stuff without being too overwhelming. If I had to come up with some constructive criticism my only real complaint would be the way you stress the word: ", AND," when you're dictating code. Coming from a background mostly in JS and python, as I'm typing along looking at my screen and mostly just listening to the video, I lost count of how many times I typed in the `and` or the `||` operators, or stopped myself just short. It's like *I* know perfectly well that you don't really mean for me to type `and`, but my *fingers* on the other hand... They fall for it nearly every time 🤣

Regarding Regex errors for both cases: you simply forgot to add a closing bracket ")" at the end of your regex expression: ``` match, _ := regexp.MatchString("(ape[^ ]?)", str) (3:01:01) r, _ := regexp.Compile("(....)") (3:02:28) ``` That's why it returned "false" - when it was supposed to return "true" - in the first example and threw an error in the "Compile" example. PS In smarter IDEs like IDEA you would actually get squiggly line warning for it.

Hi _Derek_ Have noticed you use a Mac and windows machine. How is that working out for you ? I ask as curious Linux user. Does it matter what OS one uses ?

[@derekbanas]

Hi, I actually had to use a Mac previously because a client required it. My machine learning (main) computer has been a Windows computer for many years. I do a ton of work on Linux as well because I run online stores. I could do all my ML stuff on Linux as well. I don't really think the OS matters anymore. Hardware matters some times though, but with the cheap cloud options that doesn't matter much either. The most important thing to me is to have a computer I can easily and cheaply upgrade, which is why I'll probably never own a Mac ever again.

Derek, could you cover the V language as well? It's a very interesting and powerful mixture between C, GO and Rust.😊

[@hablahei1]

One thing I didn't quite understand about the packages / modules part is why would he create a package called "myPackage" with a myPackage.go file, but then define "package stuff" at the top of that file, why not "package myPackage"? When he uses it in main he uses an alias "stuff" for that import, yet he still needs to import it from myPackage. Same goes for the name of the module. Shouldn't ideally the name of the module be the name of the project (app in this case), and the package be the name of the package/folder it's in? I feel this structure and naming would confuse me a lot if I were to jump into some kind of code base with this setup. Btw, it's not critisism, I just didn't quite understand / find it confusing.

At 1:07:36 you said creating empty slices will fill it with nils, but going through the course and trying to make an int slice that's empty I got back 0s when doing the prints.
