Go or Golang is an open source programming language developed by Google. It was released in 2009 and has since gained popularity thanks to its unique features, such as its simple syntax, its ability to create efficient programs, and its focus on simplicity and clarity.

Go is widely used in the creation of servers. This makes its community active and since Go is backed by Google, this means that we have a wealth of resources available to learn and develop our projects. Go official website

Hello world in Go

To create our hello world the first thing we must do is to create our file with the extension .go, to then insert inside this the following code:

package main

import "fmt"

func main() {
  fmt.Println("Hello World from Go!!")
}

To run this code we must have Go installed in our machine and execute the following command:

go run <path-to-your-file>

Let’s analyze the code a bit!

• 1º: We indicate that this program is executable and not a package used by other programs with line 1 in “package main”.
• 2º: We import the library “fmt” in line 3 in “import “fmt “” to be able to use the print function in console.
• 3º: We declare the function “main()” in line 4 in “func main(){}” so that it is executed at the start of our program.
• 4º: We print our “Hello World from Go!!!” in line 5 in “fmt.Println(“Hello World from Go!!!”)”.

Go has a pet!

As you can see in the title, the Go programming language has a mascot called Gopher, which you will find in many places representing Go.
