Idiom #3 Create a procedure

Like a function which doesn't return any value, thus has only side effects (e.g. Print to standard output)

var bli = function() { 
	console.log('Hello World!!!');
}
let dog = 'Poodle';
const dogAlert = () => alert(dog);
function bli() { 
	console.log('Hello World!!!');
}
const greet = who => console.log(`Hi ${who}!`)

Arrow function syntax. It consists of three parts: arguments, arrow and code block.
def finish(name):
    print(f'My job here is done. Goodbye {name}')

Variable name inside curly braces will be replaced by its value. This is called "f-strings" introduced in Python version 3.6
f = lambda: print('abc')
f()
def doSomething(name: String): Unit = {
  println(s"My job here is done. Goodbye ${name}")
}
procedure Finish (Name : String) is
begin
   Put_Line ("My job here is done. Goodbye " & Name);
end Finish;
