1. I've got a form.
2. I listen when user submit it.
3. I make a new instance of the FormData class.

  <form>
    <input type="text" name="username">
    <input type="submit">
  </form>

  const form = document.querySelector('form');
  form.addEventListener('submit', (e) => {
    e.preventDefault();
    const formData = new FormData(form);
  });

I know that formData.entries() will return an iterable, so i can use a for of loop to get the pairs... What i don't get is why this actually works:

const pairValues = Object.fromEntries(formData);

formData is an instance of a class that HAS multiple methods. Is not an iterable itself.

Does Object.fromEntries looks for an iterator by default?
