## Description
|
||
|
<section id="description"> Uma maneira fácil de anexar dados ao final de um array é por meio da função <code>push()</code> . <code>.push()</code> recebe um ou mais <dfn>parâmetros</dfn> e os "empurra" para o final do array. <blockquote> var arr = [1,2,3]; <br> arr.push (4); <br> // arr é agora [1,2,3,4] </blockquote></section>
