title: Manipulate Arrays With push()
localeTitle: Manipular matrices con empuje ()
challengeType: 1

## Description
<section id='description'>
Una forma fácil de agregar datos al final de una matriz es a través de la función <code>push()</code> .
<code>.push()</code> toma uno o más <dfn>parámetros</dfn> y los &quot;empuja&quot; al final de la matriz.
<blockquote>var arr = [1,2,3];<br>arr.push(4);<br>// arr is now [1,2,3,4]</blockquote>
