|  | ## Description
 | |||
|  | <section id="description"> Проверьте, заканчивается ли строка (первый аргумент, <code>str</code> ) заданной целевой строкой (второй аргумент, <code>target</code> ). Эта проблема <em>может</em> быть решена с помощью <code>.endsWith()</code> , который был введен в ES2015. Но для этой задачи мы хотели бы, чтобы вы использовали один из методов подстроки JavaScript. Не забудьте использовать <a href="http://forum.freecodecamp.org/t/how-to-get-help-when-you-are-stuck/19514" target="_blank">Read-Search-Ask,</a> если вы застряли. Напишите свой собственный код. </section> | |||
