características del núcleo de JavaScript como arrays hasta el explorador <a href="/es/docs/Glossary/API">APIs</a> construído sobre JavaScript. Incluso puedes crear tus propios objetos para encapsular funciones y variables relacionadas dentro de paquetes eficientes que actúan como prácticos contenedores de datos. La naturaleza de JavaScript basada-en-objetos es importante de entender, si quieres avanzar con tu conocimiento del lenguaje, y por ello hemos hecho este módulo para ayudarte. Aquí enseñamos teoría de objetos y sintaxis en detalle, y luego veremos como crear tus propios objetos.</p></div><section aria-labelledby="¿buscas_convertirte_en_desarrollador_web_de_front-end"><h3 id="¿buscas_convertirte_en_desarrollador_web_de_front-end"><a href="#¿buscas_convertirte_en_desarrollador_web_de_front-end">¿Buscas convertirte en desarrollador web de front-end?</a></h3><div class="section-content"><p>Hemos puesto un curso que incluye toda la información esencial que necesitas para alcanzar esa meta</p> <p><a href="/es/docs/orphaned/Learn/Front-end_web_developer">Comienza aquí</a></p></div></section><section aria-labelledby="prerrequisitos"><h2 id="prerrequisitos"><a href="#prerrequisitos">Prerrequisitos</a></h2><div class="section-content"><p>Antes de empezar este módulo deberías estar familiarizado con <a href="/es/docs/Glossary/HTML">HTML</a> and <a href="/es/docs/Glossary/CSS">CSS</a>.

JavaScript, la mayoría de las cosas son objetos, desde características del núcleo de JavaScript como arrays hasta el explorador APIs construído sobre JavaScript. Incluso puedes crear tus propios objetos para encapsular funciones y variables relacionadas dentro de paquetes eficientes que actúan como prácticos contenedores de datos. La naturaleza de JavaScript basada-en-objetos es importante de entender, si quieres avanzar con tu conocimiento del lenguaje, y por ello hemos hecho este módulo para ayudarte. Aquí enseñamos teoría de objetos y sintaxis en detalle, y luego veremos como crear tus propios objetos.","title":"Introducción a los objetos JavaScript","toc":[{"text":"Prerrequisitos","id":"prerrequisitos"},{"text":"Guías","id":"guías"},{"text":"Evaluaciones","id":"evaluaciones"},{"text":"Vea también","id":"vea_también"}],"pageType":"learn-module"}}</script></body></html>
