// Function Currying
//In JavaScript, functions are first-class objects, 
// just like String, Number, Boolean
//This means that they can be passed to functions or returned from functions
//

function greet(msg){
    //console.log(msg);
    return function(name){
        console.log(msg, name);
        //console.log('Hi', name);
    }
}

let english = greet('Hi');
let svenska = greet('Hej');
let espanol = greet('Hola');
let deutsch = greet('Tag');

english('Tom');
svenska('Inga');
espanol('Carlos');
deutsch('Mattias');

/*
function x(a){
    console.log('x');
    a(); //will execute function y
    return a;
}

function y(){
    console.log('y');
}

let b = x(y);  //calling function x
b();
