--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。

这个挑战可以用 ES2015 引入的 .endsWith() 方法来解决。但在这个挑战中，请使用 JavaScript 的字符串子串方法或正则表达式来通过挑战，而不要使用 .endsWith() 方法。

--hints--

confirmEnding("Bastian", "n") 应返回 true。

assert(confirmEnding('Bastian', 'n') === true);

confirmEnding("Congratulation", "on") 应返回 true。

assert(confirmEnding('Congratulation', 'on') === true);

confirmEnding("Connor", "n") 应返回 false。

assert(confirmEnding('Connor', 'n') === false);

confirmEnding("Walking on water and developing software from a specification are easy if both are frozen", "specification") 应返回 false。

assert(
  confirmEnding(
    'Walking on water and developing software from a specification are easy if both are frozen',
    'specification'
  ) === false
);

confirmEnding("He has to give me a new name", "name") 应返回 true。

assert(confirmEnding('He has to give me a new name', 'name') === true);

confirmEnding("Open sesame", "same") 应返回 true。

assert(confirmEnding('Open sesame', 'same') === true);

confirmEnding("Open sesame", "sage") 应返回 false。

assert(confirmEnding('Open sesame', 'sage') === false);

confirmEnding("Open sesame", "game") 应返回 false。

assert(confirmEnding('Open sesame', 'game') === false);

confirmEnding("If you want to save our world, you must hurry. We dont know how much longer we can withstand the nothing", "mountain") 应返回 false。

assert(
  confirmEnding(
    'If you want to save our world, you must hurry. We dont know how much longer we can withstand the nothing',
    'mountain'
  ) === false
);

confirmEnding("Abstraction", "action") 应该返回 true。

assert(confirmEnding('Abstraction', 'action') === true);

不应使用内置方法 .endsWith() 来完成挑战。

assert(!/\.endsWith\(.*?\)\s*?;?/.test(code) && !/\['endsWith'\]/.test(code));

--seed--

--seed-contents--

function confirmEnding(str, target) {
  return str;
}

confirmEnding("Bastian", "n");

--solutions--

function confirmEnding(str, target) {
  return str.substring(str.length - target.length) === target;
}

confirmEnding("Bastian", "n");
