--description--
检查字符串（第一个参数str ）是否以给定的目标字符串（第二个参数， target ）结束。这个挑战可以通过.endsWith()中引入的.endsWith()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Read-Search-Ask 。编写自己的代码。

'Walking on water and developing software from a specification are easy if both are frozen',
'specification'

不要使用内置方法.endsWith()来解决挑战。
assert(!/\.endsWith\(.*?\)\s*?;?/.test(code) && !/\['endsWith'\]/.test(code));
