2. Hello World
#golang #helloworld
To make sure that everything is running as expected let's write a quick "hello world" program.
Create a new folder where the project will live and run the following command:
go mod init helloWorld
Running the command will create the go.mod file.
We then have to create a main.go
file in the same directory.
The hello world code is shown below:
package main
import "fmt"
func main() {
fmt.Println("Hello World")
}
To simply run the code, navigate to the same directory as main.go
and execute:
go run .
To build it as a stand alone executable simply run
go build .
The beauty of go unlike other languages is that it will figure out all dependencies and packages used. No need to download them separately.
