• 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

Hello, World

• wrote the first Hello World program in 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.
