Go

Go is currently my language I am spending the most time learning next to Rust and keeping up to date on my Python and Bash knowledge.

Go promotes composition over inheritance.

Commenting Go code

Comments documenting declarations should be full sentences.
Comments should begin with the name of the thing being described and end in a period.

Error checking

You can log.Fatal(err) when playing with code.
- In actual applications you need to decide what you need to do with each error response - bail immediately, pass it to the caller, show it to the user, log it and continue, etc ...

Notes

I can call functions from anywhere if they are in the same package.
The package “main” tells the Go compiler that the package should compile as an executable program instead of a shared library.
Note that any type implements the empty interface interface{} because it doesn't have any methods and all types have zero methods by default.
Simply pushing my source code to GitHub, makes it go gettable.
Interface types represent fixed sets of methods.
the prevailing wisdom in Go is to use a flat directory structure and only create new directories when you are building self-contained functionality.
go get = download the source code to your PC.
go install = download, build, and put it in the path so you can use it.
I don't need to comment all functions as some are self describing. I do need to comment exported functions however.
What works well is to use Go to create an HTTP API and leave the rest (html templates etc) to a client-side frontend (e.g. React). That gives you the best of both worlds: a fast and lightweight backend in Go with a rich frontend in JS.
This is a core concept in Go’s type system; instead of designing our abstractions in terms of what kind of data our types can hold, we design our abstractions in terms of what actions our types can execute.
In Go, as long as you are not sharing data, you don't really have to care about whether something is concurrent or parallel, the runtime takes care of it for you. You just use goroutines, IO transparently happens on a dedicated threadpool, CPU heavy tasks are spread out over the available cores.
How to edit Go packages locally
The main sell point of Go is not simplicity, but overall balance and flexibility
