  </form>

  <p id="text"></p>

  <script>
    let form = document.querySelector('form'),
    input    = document.getElementById('input'),
    text     = document.getElementById('text')

    form.addEventListener('submit', (e) => {
      e.preventDefault() // منع الافتراضي الي هو تحديث الصفحة لارسال البيانات للسيرفر
      text.innerHTML = input.value
    })
  </script>   
</body>
