Reactividad: Manipulaci\u00f3n NO Reactiva del DOM"},"content":{"rendered":"\n

Para entender el concepto de reactividad<\/strong> vamos a trabajar a lo largo de estos cap\u00edtulos en un ejercicio para que entendamos bien como funciona. Crearemos una carpeta dentro de nuestro servidor a la que llamaremos justamente reactividad,<\/em> y el primer archivo que vamos a crear se va a llamar dom-manipulacion.html<\/em>, donde lo que vamos a hacer es una manipulaci\u00f3n b\u00e1sica del DOM<\/strong> de un formulario que vaya agregando a una lista de tareas m\u00e1s tareas.<\/p>\n\n\n\n\n\n\n\n

Sintaxis de dom-manipulacion.js<\/em> (sin reactividad<\/strong>).<\/p>\n\n\n\n

El siguiente paso que haremos en el siguiente cap\u00edtulo es, esta manipulaci\u00f3n com\u00fan y corriente del DOM<\/strong> que ya hemos visto, como podemos pasarla para que esa interfaz visual sea una interfaz basada en el estado<\/strong>, es decir, crear una variable que manipule todos los datos de la aplicaci\u00f3n, y cuando haya alg\u00fan cambio, entonces renderice ese cambio.<\/p>\n","protected":false},"excerpt":{"rendered":"
