Why is Go syntax so messy (lemmy.ca)

I understand Rust being type safe, but Im seeing syntax that Ive never seen in my life in Go which looks too messy

var test int < bruh what?

:=

func(u User) hi () { ... } Where is the return type and why calling this fct doesnt require passing the u parameter but rather u.hi().

map := map[string] int {} < wtf

The := operator is called walrus operator and is inspired by Python I think. It's declaring a variable and assigning it in one go. map[string] int is defining a map (associative array or also known as dictionary in Python), with string as key type and int as value type. And the following {} is the body of the associative array, meaning empty content.

I only played a bit with Go and did basic tutorials. I might go back to it at some point, but Zig is much more appealing to me. Go is too simple in the language to me, but on the other side, this is exactly whats appealing.

@thingsiplay @urska I love this, I've been learning some VBA lately and it uses this. I'm much happier knowing it's got an adorable name.
