Go

Variables

Variables are defined as:

var name type = value

For example:

var x string = "Hello"

The type can be inferred if an initial value is given, e.g.

var x = "Hello"

or by using the := operator:

x := "Hello"

Constants can be defined by using the const keyword instead of var.

Loops

Go only supports the for loop - unlike other languages it lacks while, do while etc. However, it is possible to emulate other loop constructs using for.

Imports

Standard import notation:

import "fmt"

Multiple imports can be done either one line at a time or as a group:

import (
  "fmt"
  "math"
)

Names in packages are exported if they begin with a capital letter.
