## Description
|
||
|
|
<section id='description'>
|
||
|
|
Hasta ahora, solo ha podido extraer o buscar un patrón una vez.
|
||
|
|
<blockquote>let testStr = "Repeat, Repeat, Repeat";<br>let ourRegex = /Repeat/;<br>testStr.match(ourRegex);<br>// Returns ["Repeat"]</blockquote>
|
||
|
|
Para buscar o extraer un patrón más de una vez, puede usar la bandera <code>g</code> .
|
||
|
|
<blockquote>let repeatRegex = /Repeat/g;<br>testStr.match(repeatRegex);<br>// Returns ["Repeat", "Repeat", "Repeat"]</blockquote>
