Help! - ES6: Compare Scopes of the var and let Keywords

Tell us what’s happening:
I can’t understand why the output is 3 in this challenge. The loop already encountered a return statement the loop should stop and the increment for variable i should not happen? Am I right?? or Am I missing something?

Your code so far

var printNumTwo;
for (var i = 0; i < 3; i++) {
  if (i === 2) {
    printNumTwo = function() {
      return i;
// returns 3

Challenge: Compare Scopes of the var and let Keywords

Link to the challenge:

the loop declaration is inside the function, but the function is actually executed only once it’s called in the last line outside of the loop

Hello @ilenia! Super thanks! hehe

I was confused. The function was initialize in the variable printNumTwo! That’s why it did not stop the loop. And the value of i is 3.
