<p><strong>WebAPI</strong> é um termo utilizado para referir um conjunto de compatibilidade de dispositivo e APIs de acesso que permitem que as aplicações da Web e o conteúdo acedam ao dispositivo de hardware (tais como estado da bateria ou hardware de vibração do dispositivo), bem como aceder aos dados guardados no dispositivo (tais como o calendário ou lista de contactos). Ao adicionarmos estas APIs, nós esperamos que expanda o que a <em>Web</em> pode fazer hoje, para também incluirem o que apenas as plataformas proprietárias podiam fazer no passado.</p>
<div class="note">
