Você pode até criar seus próprios objetos.É importante entender a natureza orientada a objetos do JavaScript se você quiser ir mais longe com seu conhecimento da linguagem e escrever um código mais eficiente, portanto, fornecemos este módulo para ajudá-lo. Aqui ensinamos a teoria e a sintaxe de objetos em detalhes, observamos como criar seus próprios objetos e explicamos quais são os dados JSON e como trabalhar com eles.</p>\n</dd>\n<dt id=\"javascript_assíncrono\"><a href=\"#javascript_assíncrono\"><strong><a href=\"/pt-BR/docs/Learn_web_development/Extensions/Async_JS\">JavaScript Assíncrono</a></strong></a></dt>\n<dd>\n<p>Neste módulo, examinamos o JavaScript assíncrono, por que é importante e como ele pode ser usado para lidar efetivamente com possíveis operações de bloqueio, como a busca de recursos de um servidor.</p>\n</dd>\n<dt id=\"apis_web_do_lado_cliente\"><a href=\"/pt-BR/docs/Learn_web_development/Extensions/Client-side_APIs\">API's Web do lado cliente</a></dt>\n<dd>\n<p>Ao escrever JavaScript para sites ou aplicativos da Web, você não vai muito longe antes de começar a usar APIs - interfaces para manipular diferentes aspectos do navegador e do sistema operacional em que o site está sendo executado, ou até dados de outros sites ou serviços. Neste módulo, vamos explorar o que são as APIs e como usar algumas das APIs mais comuns que você encontrará com frequência em seu trabalho de desenvolvimento.</p>\n</dd>\n</dl>"}},{"type":"prose","value":{"id":"aprofundando","title":"Aprofundando","isH3":false,"content":"<p>Uma vez que você se acostumar com o mundo do JavaScript aqui estão
