// 1: What is the expected output? And why?

function print() {
  console.log(1);
  setTimeout(() => console.log(2), 1000);
  setTimeout(() => console.log(3), 0);
  console.log(4);
}

print(); // => ???

// ------------------------------------------------------------------------

// 2: Use setTimeout() to print 'I am printing after ___ seconds.' 
// depending on how much delay is passed to setTimeout as delay.

// Example: when calling printing(3) as a callback of setTimeout(),
// it should print 'I am printing after 3 seconds.' when 3 seconds pass.
// When calling printing(7) as a callback of setTimeout(),
// it should print 'I am printing after 7 seconds.' when 7 seconds pass.

function printing(delay) {
  // ... your code here
}
setTimeout(/* invoke printing here */);
setTimeout(/* invoke printing here */);

// ------------------------------------------------------------------------

//3: Countdown from 10 to 0. When the countdown is zero, it should show “Pop!” and stop the interval.

let i = 10;
const intervalId = setInterval(/* your code here */)

// ------------------------------------------------------------------------

// BONUS: Write a script that prints  'Ironhack -> __ sec.' after every delay.
// Example, if you start with the delay of 1 second, it  should print 'Ironhack -> 1 sec.'
// After that, the delay should be incremented by 1 second each time.
// After 2 seconds, it should print 'Ironhack -> 2 sec.'
// Then the delay should be 3 seconds, so after that time, it should print 'Ironhack -> 3 sec.'
// And so on.

function printIronhack(delay) {
  // ... your code here
}
printIronhack(1);
