## Description
|
|
<section id='description'>
|
|
En el último desafío, aprendiste a usar el carácter de <code>caret</code> para buscar patrones al principio de las cadenas. También hay una forma de buscar patrones al final de las cadenas.
|
|
Puede buscar el final de las cadenas con el <code>dollar sign</code> <code>$</code> al final de la expresión regular.
|
|
<blockquote>let theEnding = "This is a never ending story";<br>let storyRegex = /story$/;<br>storyRegex.test(theEnding);<br>// Returns true<br>let noEnding = "Sometimes a story will have to end";<br>storyRegex.test(noEnding);<br>// Returns false<br></blockquote>

|
|
testString: 'assert(lastRegex.source == "caboose$", "You should search for <code>"caboose"</code> with the dollar sign <code>$</code> anchor in your regex.");'
|
|
- text: Su expresión regular no debe usar ninguna bandera.
|
|
testString: 'assert(lastRegex.flags == "", "Your regex should not use any flags.");'
|
|
- text: Debe coincidir con <code>"caboose"</code> al final de la cadena <code>"The last car on a train is the caboose"</code>
|
|
testString: 'assert(lastRegex.test("The last car on a train is the caboose"), "You should match <code>"caboose"</code> at the end of the string <code>"The last car on a train is the caboose"</code>");'
