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.
Thank you for the nice compliment :) I'm very happy you enjoy my videos.
finally! the Go-lang gopher made it to the Derek's show, thanks!
I hope you find it useful :)
@@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?
YOU'VE MADE ME BETTER - MUCH LOVE FROM NEW ORLEANS BROTHER ♥️💪
"The key point here is our programmers... They’re not capable of understanding a brilliant language...So, the language that we give them has to be easy for them to understand"
―Rob Pike
@VexCode 😂
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
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. :)
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!
This is the absolute best GoLang tutorial for intermediate devs just getting started with Go. I say this as someone who took 2 paid courses on Udemy and this one wins hands down! Thank you 🙏
@@matthewb192 yep , most of those courses are outdated as well . The top most web dev course was launched in 2017 i guess .
Derek- a really fine job! You have a natural ability to communicate.
Amazing tutorial! Love the way you teach Derek!
This course is amazing, just what I was looking for
Thank you very much!
Once again, your help is invaluable. Thank you Derek
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 =]
thanks :D.
You are always the best Derek!
You are a legend! This course is exactly what I needed to learn Go without having to skip the parts explaining variables and functions.
dude you HELP A LOT THANKS. Awesome job. You make people more educated for free w/o ads, you're legend. Again THANKS!
Perfect course that I was seeking nowadays, Thank you, You are the BEST.
Thank you :) I'm happy I could help
Thank you! now, I can practice go myself. Great!
I guess I need more than the current existing human languages to thank you enough for you amazing and useful vides !
You're great !
Thank you for the nice compliment :) I'm happy I can be of help
Thanks, for years you have taught me nearly everything lol.
You're nothing short of a legend for real
dude. absolute beast. I can tell you put a lot of work into this. respect
I'll second that!
i second that as well the man really tried
Great tutorial. I enjoyed it and practiced while watching..
Just discovered your channel with your Dlang tutorial! Insta-subscribed! :D
Cheers from Argentina! Love your content.
Thank you very much :) I'm happy you are enjoying the videos
1:23:17 - Trying to cast a spell XD
Thanks for the video!
Let's all appreciate the creators for this such a good work.
Thank you :) I'm happy I could help
amazing tutorial, can't love it more
"এতোদিন কোথায় ছিলেন?"-- in English, "where were you for so so long, my love?!"
Thanks a lot. It's great help.
Thank you very much :) I'm happy I could be of help
Perfect tutorial, just what I was searching for. ♥♥♥♥♥♥♥♥♥♥
Thank you :) I'm happy you found it useful
I just watched your previous video on golang from 2015 yesteday and now there is the new version !
I upgraded this version a lot. I hope it helps
This course is awesome! I'm going to share it with everyone in my engineering org once I finish!
Thank you very much :) I'm happy you are enjoying it!
Great work, thanks! A small typo report - in the table of contents it should be "Variadic" in the 1:13:11 Varadic Functions
You are the great educator. Im following you since i started programming thts 4 yrs back. Till now if i want to study new language i will search for you video first and proceed with my path. You are kinda Less talk more work. Keep it up.👍
I have gone through Instructors who will talk for 10mins and teach for 5mins😥
Thank you for the nice compliment :) My goal with every video is to cover as much as possible as fast as possible. I don't like to waste peoples time.
Absolute gigachad. Thanks!
@derekbanas great tutorial, thank you very much! I remember watching your Java courses when I was at college! I still watch your courses years later! Thank you so much!!
(Do you mind sharing Font-Type you use in VSCode, looks really good!)
Thank you :) I use Consolas
Thanks for this awesome tutorial 🙌🏼
Thank you :) I’m happy you enjoyed it
If you don't now There's Global two functions for Printing out print and println both lowercase so you use instead to alias fmt just use for Formatting such Printinf, Sprintf or Fprintf
Thanks for your effort always
Thank you :) I forgot to cover them.
Just a quick question before jump in. Do you cover workspaces, generics and all the stuff offered after Go 1.18?
All I can say, again, thanks very very much!
Thank you very very much :) I couldn't do it without you
You are the best Derek Banas
Thank you for saying that :) I hope you find the course useful
Cool stuff, senior dev here, I set speed at 1.5, and use the right arrow a lot and basically learned (reading level / copilot partner) go in 1 hour. Very useful to not have to spend time getting to the info
i have 0 go knowledge , will this course give me all the basics from which i can build on
I loved this tutorial, just a little note here, in the Regular Rxpressions part you had an error not because of vs code but because the regular expression was missing the closing parenthesis
Thank you :) Sorry about the bug
Me: starts learning Go yesterday
Derek: Here.
package main
import "fmt"
func main() {
fmt.Println("Thank you")
}
@@-Pls- :D keep on learning!
I'm very happy that I could help :)
or, even better, without any "import"
package main
func () {
print( "Thanks a lot Derek")
}
Thank you sooo much for excellent content 💕🙏👌🤞👏🙌👍✌
Thank you :) I'm happy I could help
Wow. You’re a legit G.
Very Good video, well explained. Thank you!
Thank you very much :)
Thank you
@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 🤣
Great content, appreciate it.
Thank you very much :)
The Man, The Myth, The Legend!
Thanks for making programming more accessible to non-readers!
Could you do Racket or OCaml someday?
Lol! I was checking if he did those exact two languages today :)
3:21 would "var pl" be better as "const pl" or there is a reason why it's better as a var?
Can i ask you if this tutorial is for beginners ? because just watch a couple minutes doesn't explain much on the values your using and what the mean ? thank you
Danke!
Great job!
Thanks Stan :)
It is great, thank you
Your last two tutorials are the best ones in the channel!
What’s going to be next Scala 3 or Coq?
Thank you :) x64 assembly language
@@derekbanas sensing a low level theme here 📟
@@derekbanas For when something different is on the agenda, may I suggest Unreal Engine 5
Super!!! Thanks!!!
Thank you :)
Do you reckon that you could make some sort of course on Kubernetes? :)
Just as an update for those using VSCode - setting "experimentalWorkspaceModule" in the gopls settings is no longer required =]
just what I'm looking for
Hey Derek: A little off-topic, but what software was used for that newsroom style stream in one of the videos from before? (Looked very newsroom and maybe had a text scroller or similar) Thanks in advance!
I used After Effects mainly. I have a tutorial here on how I made it czcams.com/video/20MnU0at4_E/video.html
@@derekbanas Saw now! Wow, thanks!
Am looking at learning Go language and am like who do i go to ,who do i learn this from after searching for a while ,i stumbled into your channel and am like this is the final bus stop you nailed it man , thanks
best fast tut well played
Thank you are my Mentor!.
It is my pleasure to be able to help :)
Where are you from @Derek that "Rune" is two syllables? (But seriously, love your videos. Thank you).
Thank you :) I live in Pittsburgh where we mispronounce everything.
@@derekbanas LOL.
Thank you❤
Hello Derek.
Maybe a bit unrelated, how did you configured VS Code to run go programs?
specifically, the small "play" icon on the top right of the editor pane that executes the "go run " on the terminal?
I used Code Runner. I show the installation at the end of the video
the best I could find
nice. with dark bg at last
2:55:25
Passing functions. For future references, remove the comma after the y
func useFunc(f func(int, int) int, x, y, int) {
to
func useFunc(f func(int, int) int, x, y int) {
No data connect and CRUD? What service does it run on? Hosting companies cover it?
Isn't there supposed to be a switch statement as well ??
Maybe defer as well
Thanks! 👏👏👏
I’m happy you enjoyed the video :)
thank you 😊
I'm happy I could help :)
the course u provide is it coving real projects using go? , im django developer and i want to begin my trip with go
This is my google for learning go lang for now
I'm glad you like it :) I'll be posting a 100% FREE Golang Udemy course soon. Click notifications to be alerted.
Thanks!
Thank you so much for the support! I'm happy you found value in my Go video.
Thanks, how can get the split icons in the top-right of the window/menu bar in your video?
Sorry, but I'm not sure what you are referring to?
@@derekbanas What are the buttons on the left side of Minimum/Maximum/Close buttons in the window bar 02:00
@@derekbanas It seems those icons are already there by default after you install it on Windows, but I'm on Linux, I watched a few videos about vscode installation on Windows and Linux, no such icons for vscode on Linux.
@@derekbanas Found the solution: `"window.titleBarStyle": "custom"` in settings.json or in Preference page, search "window: title bar style", choose "custom"
wow this is amazing. Quick question: Is this like a zero to professional course or just for beginners only?
Thank you. The goal with this course was to make the most complete course on Golang on CZcams.I covered more here than you'll find in any book.

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 ?
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.
@@derekbanas *Bravo!* thanks for tanking the time to reply in detail
On windows there is WSL2..windows sub system for linux, so one can run Ubuntu or whatever linux distro very easily, it works great. When it comes to deployment linux seems to dominate.
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.
FYI, don’t use log.Fatal() after a defer statement, because log.Fatal() calls os.Exit(1) that quits the program immediately, and itprevents any deferred instruction from running.
how the Fudge can I save this video... this is awesome.
Hey, do you think it's possible/ feasible for you to make an updated video on java? Your java tutorials are close to a decade old now.
Here are my updated Java Tutorials

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.
Hi derek! Can you please make an updated video on c#?
My next video will be on C# and it will be huge
Would be interesting to see a day in your life
we need a full tutorial on tensorflow
youre finally actually making good videos
this is awesome
Thank you for taking the time to tell me I helped :) I appreciate it!
I would be so stupid without youtube in my life
there are a lot of things which i couldn't understand like reader, log what is this
Derek is on fire
I try to do my best :) Thanks
after covering algebra, linear algebra , precalculus, lemme guess your next all in one video is calculus(1,11 & 111)
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. Strings came back empty though! Expand to see below code snippet.
```
// creating an empty int slice
sl4 := make([]int, 6)
fmt.Println(sl4)
```
Sorry about that. I misspoke. I think at some point in the video I say what the default value is for each data type. It's basically 0, 0.0, false, nor null
Derek, could you cover the V language as well? It's a very interesting and powerful mixture between C, GO and Rust.😊
Cool
please make calculus 1, 2 series
