What will the value of `i` be in the alert box when `first()` and `tenth()` are called?

closureTest.js

function makeGalaxy(size) {
  var stars = [];
  for (var i = 0; i < size; i++) {
    stars.push(function(){alert("This is star #" + i);});
  }
  return stars;
};

var galaxy = makeGalaxy(20);

var first = galaxy[0];
first();

var tenth = galaxy[9];
tenth();

Changes to makeGalaxy to have it behave as expected:

function makeGalaxy(size) {
  var stars = new Array(size).fill(0);
  return stars.map((star, index) => {
    return () => {alert(`This is star #${index}`)};
  });
}
