Hello Friends, Today we will understand and write our Golang code from scratch. We will go through the pre-requisites and later will go through the code.
The requirement for running GO.
For executing any go program, the following steps must be followed. We must have Go binaries installed on our machine. for that please follow the steps in the link
Writing Hello Go Example
Save the below code in the main.go file.
package main
import "fmt"
func main() {
fmt.Println("Hello World")
}

Run the code by running the below command.
go run main.go
Understanding the program
- package is used to tell which component it belongs to. for our example, it is in the main package.
