Just working through The Go Programming Language book by Donovan and Kernighan.

:= is short variable delcaration

++ and -- are statements, not expressions, so i++ is valid, but j = i++ is not

_ is the blank identifier

Preferred init of strings

When the initial value is important

// can't be used for package level variables s := ""

When the default value for the type, "" for strings, is okay

var s string

Loops

for loop

for initialization; condition; post { ... }

traditional while loop

for condition { ... }

infinite loop

for {

}

loop over range

for _, arg := range slice { ... }

Structs

type person struct { name string age int }

joe := person{ name: "John", age: 32, }

joe.name
