## Description
|
||
|
|
<section id='description'>
|
||
|
|
Otro tipo de datos es el <dfn>booleano</dfn> . <code>Booleans</code> solo pueden ser uno de dos valores: <code>true</code> o <code>false</code> . Básicamente son pequeños interruptores de encendido y apagado, donde <code>true</code> está "encendido" y <code>false</code> está "apagado". Estos dos estados son mutuamente excluyentes.
|
||
|
|
<strong>Nota</strong> <br> <code>Boolean</code> valores <code>Boolean</code> nunca se escriben entre comillas. Las <code>strings</code> <code>"true"</code> y <code>"false"</code> no son <code>Boolean</code> y no tienen un significado especial en JavaScript.
