Golang quick reference: Hello World

package main

import "fmt"

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

package main:

Every Go program starts with a package declaration. The main package is the entry point for the Go compiler.

import "fmt":

This imports the "fmt" package, which provides functions for formatted I/O operations.

func main() {:

The main function is where our program starts executing. Every Go program must have a main function in the main package.

fmt.Println("Hello World!"):

This calls the Println function from the "fmt" package to print "Hello World!" to the console.

Run your program by typing go run <filename>.go. Happy coding!
