GoLangNotes.md

• Does not support nested functions
  • Must use variable/lambda assignment:

func main() {
	test := func() {
		println("Hello")
	}

	test()
}

• Uses go keyword for threading stuff:

func main() {
  go func() {
		println("Hello")
	}()
}

• No Array.prototype.map alternative - Not an FP language

• No generics until v2 (https://go2goplay.golang.org/)

• chan used for multi-go routing communication

  • Cannot be accessed using indices

• range supports indexes and values but not on chan (only values)

• no Turnary https://stackoverflow.com/questions/19979178/what-is-the-idiomatic-go-equivalent-of-cs-ternary-operator

• No range() method like there is in Python, instead use typical for loops https://stackoverflow.com/questions/21950244/is-there-a-way-to-iterate-over-a-range-of-integers

Commands

• go mod init to start project
• go run file.go to run project

Use go install instead:

Install the latest version of a program,

ignoring go.mod in the current directory (if any).

$ go install golang.org/x/tools/gopls@latest

Install a specific version of a program.

$ go install golang.org/x/tools/gopls@v0.6.4

Install a program at the version selected by the module in the current directory.

$ go install golang.org/x/tools/gopls

Install all programs in a directory.

$ go install ./cmd/...

Switch case based on type https://tour.golang.org/methods/16

Using the 'go doc' command is helpful. You can find out more about a package. Or about a function inside the package. EXAMPLE: go doc time. Now
