Você pode até mesmo criar seus próprios objetos para encapsular funções e variáveis relacionadas em pacotes eficientes e atuar como contêineres de dados úteis. É importante entender a natureza baseada em objetos do JavaScript se você quiser aprofundar seu conhecimento da linguagem, portanto, fornecemos este módulo para ajudá-lo.

JavaScript, a maioria das coisas são objetos, desde os principais recursos do JavaScript, como arrays, até o navegador APIs construído sobre o JavaScript. Você pode até mesmo criar seus próprios objetos para encapsular funções e variáveis relacionadas em pacotes eficientes e atuar como contêineres de dados úteis. É importante entender a natureza baseada em objetos do JavaScript se você quiser aprofundar seu conhecimento da linguagem, portanto, fornecemos este módulo para ajudá-lo. Aqui ensinamos a teoria e a sintaxe de objetos em detalhes, depois veremos como criar seus próprios objetos.","title":"Introdução a objetos em Javascript","toc":[{"text":"Pré-requisitos","id":"pré-requisitos"},{"text":"Guias","id":"guias"},{"text":"Avaliações","id":"avaliações"},{"text":"Veja também","id":"veja_também"}],"pageType":"learn-module"}}</script></body></html>
