I've been following this course on Go each day as the videos come out. I find its just enough for me to go play with it and reinforce my learning as I go. I not only retain more but I gain a deeper understanding. Thanks for the great videos.

Shaun, this is the best course of GO for beginners in this kind of languages. I was trying to get started with GO (coming from JavaScript) and it was so hard but you make learning GO as simple as learning Python. You are definitely the best instructor.

Just discovering Go. Thanks for making these tutorials.

incredibly clear tutorial, thanks and congrats!

Mmm, a typed language with proper arrays and c-style string formatting. All in.

Will save this playlist for future purposes...just in case🙃

your coures are so up to the point. the udemy courses I do are 30 to sometimes 50hrs long which makes me lose interest in them

Awesome tutorial! You are explaining it so well!

[osamagamal]

Hello, will you continue the Django tutorials?
I think you could make more videos about for example implementing the app into the webhost.

Nice videos Ninja, a kotlin playlist would do nicely!

Would love to see Rust and Elixir with Phoenix also in the future!

I am a golang beginer and I just have a warning anout slices and append.
I loose hours because of a code like:
path := []stuff{s1, s2, s3}
Then later in a slice of slice I have a loop with something like:
for _, s := range steps {
currentPath := append(path, s)
sliceOfSlice = append(sliceOfSlice, currentPath)
}
And here started my problems. Everything work as expected until I reach a certain point. The code behave like I append in the sliceOfSlice several time the last value of currentPath.
This is because I reached the capacity of path. The ugly fix I found is to create a new slice with a capacity of path + 1, then add the content of path + s:
currentPath := make([]stuff, 0, len(path)+1
currentPath = append(currentPath, path...)
currentPath = append(currentPath, s)
Do you have a better fix than this?

In your array name := [4]string{"yoshi", "mario", "peach", "browser"}. What happened if I print only 1 item in an array ?

Hey Shaun, please make such tutorials on Rust, please. this one doesn't have any good tutorials on youtube, you would be firstand people need quality Rust tuts

[MikeNugget]

What is the use case of arrays with immutable length?

[basickarl]

Good tutorial! But boy am I disappointed in Go's syntax...

[mulllaya]

Alright I watched it.
And it feels like GO is just a dodgy version of JS. Even dodgier than TS.
However I heard it’s pretty popular and many companies moving their backend from Python to GO.
