I can't understand why is the output is -96 of this code

Question

I actually expect that output should be 101 during the first iteration and 3 during the second iteration but it's actually -96 for both iterations. Here is the code

const arr = [];

for (var i = 100; i > 0; i = i - 99) {
  arr.push(function () {
    console.log(i);
  });
  i = i + 1;
}

arr.forEach((item) => item());
