Go

Totally clueless newbie on this one.

Syntax speedrun

Pointers

• * is used to declare a pointer.
• & is used to get the address of a variable you’re pointing to, or want to point to.

var x int = 1
var y = &x // y holds variable x's memory address

var y *int = &x

Variables

var x int = 1
var x = 1
x := 1

Functions

func learnNamedReturns(x, y int) (z int) {
    //...
}

Testing

Ending a file’s name with _test.go tells the go test command that this file contains test functions. ¹

To run tests:

go test

# to see all of the tests and their results
go test -v 

Troubleshooting

“Cannot find package github.com/…/… in any of ….” when running go get:

• Try GO111MODULE=on first.
