The anatomy of Functions in Go

Like JavaScript, functions in Go are first-class citizens. They can be assigned to variables, passed as an argument, immediately invoked or deferred for last execution.

☛ What is a function

A function, in general, is a small piece of code that is dedicated to a perform particular task based on some input values. We create a function so that we can perform such an operation whenever we want from wherever we want by providing some input values.

These input values provide extra information to a function and they are totally optional. A function’s execution may or may not return any result.

In Go, a function is defined using func keyword.

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

This function can be called from anywhere inside a function body in the program. For example, we have a dosomething function that prints some characters to the standard output.
