|  | ## Description
 | |||
|  | <section id="description">检查字符串(第一个参数<code>str</code> )是否以给定的目标字符串(第二个参数, <code>target</code> )结束。这个挑战<em>可以</em>通过<code>.endsWith()</code>中引入的<code>.endsWith()</code>方法来解决。但是出于这个挑战的目的,我们希望您使用其中一个JavaScript子字符串方法。如果卡住,请记得使用<a href="http://forum.freecodecamp.org/t/how-to-get-help-when-you-are-stuck/19514" target="_blank">Read-Search-Ask</a> 。编写自己的代码。 </section> | |||
