• Designed as a "systems" language
• Good all-rounder
• Syntax like C but simpler
• Garbage collection
• 25-ish keywords
• Compiled
• Strongly-typed
• Functions are first class citizens
• Capitalise routines that you want to expose

Go workspace

~/go/
	src
	pkg
	bin

Type inference

auto a = 10;
auto b = 10.0;

a := 10
b := 10.0

int main () {
}

package main
import {
	"fmt"
	"runtime"
}

func main() {
	fmt.Println("Hello from ", runtime. GOOS);
}

Compile and run

go run hello.go

Variables and contants

Go passes by value not reference.

var name string = "Ken"

Initialise at declaration

// Package level declaration
var {
	first, second, age = "kenny", "key", 70.0
}

// Local declaration
func main() {

	// Use := operator when declaring, = when assigning
	a := 10
	const b = 10.0
}
