## Description
|
|
<section id='description'>
|
|
Using regexes like <code>/coding/</code>, you can look for the pattern <code>"coding"</code> in another string.
|
|
This is powerful to search single strings, but it's limited to only one pattern. You can search for multiple patterns using the <code>alternation</code> or <code>OR</code> operator: <code>|</code>.
|
|
This operator matches patterns either before or after it. For example, if you wanted to match <code>"yes"</code> or <code>"no"</code>, the regex you want is <code>/yes|no/</code>.
|
|
You can also search for more than just two patterns. You can do this by adding more patterns with more <code>OR</code> operators separating them, like <code>/yes|no|maybe/</code>.
