node js tricky code questions with asnwers

Comment

for (var i = 0; i < 5; i++) {
  setTimeout(() => {
    console.log(i);
  }, 0);
}

The code will print 5 five times.
This happens because of the closure capturing the reference to the variable i AND
NOT It's value at the time of the closure creation.

By the time the callbacks are executed, the loop has already finished, 
and i has the value of 5.
