## 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 "empuja" al final de la matriz.
|
||
|
|
<blockquote>var arr = [1,2,3];<br>arr.push(4);<br>// arr is now [1,2,3,4]</blockquote>
