Function In JavaFX

Function concept in JavaFX is so simple like in Javascript:

function hello(name:String){

    println("Hello, {name}!");

}

To call it, use:

hello("Lady Gaga");

Other samples:

function add(x:Integer,y:Integer){

    println("Add: {x} + {y} = {x+y}");

}

function add(x:Integer,y:Integer){

    return x+y;

}
