 <p>Funkcja <strong><code>WindowBase64.atob()</code></strong> dekoduje ciąg danych, który został zakodowany używając kodowania base-64. Możesz użyć metody <a href="/pl/docs/Web/API/WindowBase64.btoa"><code>window.btoa()</code></a> aby zakodować i przesłać dane, które w innym wypadku mogą powodować problemy z komunikacją, a następnie odebrać je i użyć metody <code>window.atob()</code> aby zdekodować dane ponownie. Na przykład możesz zakodować, przesłać i zdekodować znaki kontrolne ASCII o wartościach od 0 do 31.</p>
