// Callbacks

// Complete this function so that it passes the numbers 1 and 2 into the callback
function two_numbers(callback){
  // TODO
}

two_numbers(function(x, y){
  console.log(x, y);
}

// Async and callbacks

// Complete this function using setTimeout to only pass the message to the callback
// after the defined delay
function afterTimeout(message, delay, callback) {
  // TODO
}

function afterTimeout("hello world", 1000, function(message){
  console.log(message);
})
