Greeting Quadri Shittu!! Congratulations on completing your challenge!, 👏👏👏

I didn't finish this challenge yet, but I think the easy way to add that spacing is to track the input value length and add a space to the value when hint a four number.

example function .

function addSpacing(input) {
  if (
    input.value.length == 4 ||
    input.value.length == 9 ||
    input.value.length == 14
  ) {
    input.value += " ";
  }
}

Hope this give you some hints.

Happy Codding, have a Good Day
