Handling Forms & User Input

What form handling pattern does this implement?

form.addEventListener('submit', e => {
  e.preventDefault();
  if (form.reportValidity()) {
    const data = new FormData(form);
    for (const [name, value] of data) {
      sessionStorage.setItem(name, value);
    }
  }
});

Form data persistence
This implements form data persistence using sessionStorage: 1) Validates form before saving, 2) Preserves form data across page reloads or navigation, 3) Useful for multi-step forms or saving work in progress, 4) Data persists until browser session ends, 5) Can be combined with window.onload to restore form state. Consider using localStorage for longer-term persistence or IndexedDB for larger data sets.
