Go, also known as Golang, is a statically-typed concurrent programming language made by an engineer team at Google.^[8][9]

Example

Here is a hello world program in Go.

package main
// Import fmt library through the standard library.
import "fmt"

// Define entry point.
func main() {
    // Write to output.
    fmt.println("Hello world!")
}
