Installed Go to my Macbook with brew install go
To check whether Go is installed or not use go in the terminal and if it returns some commands that can be combined with go

package main
import 'fmt'
func main() {
     fmt.Println("Hello, World")
}

compiled the helloworld.go with go build helloworld.go which created an executable.
executed with ./helloworld
We can compile and execute with a single command go run helloworld.go which didn't create any executable file.

variables in go can be declared in the following ways

var a int
var b bool
a = 15 
b = true


var (
x int
y bool
)
x=100
y=false

m:=100
n:="New N"

var i,j int
i=1
j=2
