## Description
有时您不会（或不需要）知道模式中的确切字符。想到所有匹配的单词，比如拼写错误需要很长时间。幸运的是，您可以使用通配符来节省时间： .通配符.将匹配任何一个字符。通配符也称为dot和period 。您可以像使用正则表达式中的任何其他字符一样使用通配符。例如，如果你想匹配"hug" ， "huh" ， "hut"和"hum" ，你可以使用正则表达式/hu./来匹配所有四个单词。 让humStr =“我会哼唱一首歌”;
让hugStr =“熊抱”;
让huRegex = /hu./;
humStr.match（huRegex）; //返回[“hum”]
hugStr.match（huRegex）; //返回[“拥抱”]
## Instructions
完成正则表达式unRegex ，使其匹配字符串"run" ， "sun" ， "fun" ， "pun" ， "nun"和"bun" 。你的正则表达式应该使用通配符。
## Tests
```yml
tests:
- text: 您应该使用.test()方法。
testString: 'assert(code.match(/\.test\(.*\)/), "You should use the .test() method.");'
- text: 您应该在正则表达式unRegex使用通配符
testString: 'assert(/\./.test(unRegex.source), "You should use the wildcard character in your regex unRegex");'
- text: 你的正则表达式unRegex应该匹配"run" "Let us go on a run." "run"中的"run" "Let us go on a run."
testString: 'assert(unRegex.test("Let us go on a run."), "Your regex unRegex should match "run" in "Let us go on a run."");'
- text: 你的正则表达式unRegex应该与"sun" "The sun is out today." "sun"中的"sun"匹配"The sun is out today."
testString: 'assert(unRegex.test("The sun is out today."), "Your regex unRegex should match "sun" in "The sun is out today."");'
- text: 你的正则表达式unRegex应该与"fun" "Coding is a lot of fun." "fun"中的"fun"匹配"Coding is a lot of fun."
testString: 'assert(unRegex.test("Coding is a lot of fun."), "Your regex unRegex should match "fun" in "Coding is a lot of fun."");'
- text: 你的正则表达式unRegex应该匹配"pun" "Seven days without a pun makes one weak." "pun" "Seven days without a pun makes one weak."
testString: 'assert(unRegex.test("Seven days without a pun makes one weak."), "Your regex unRegex should match "pun" in "Seven days without a pun makes one weak."");'
- text: 你的正则表达式unRegex应该与"nun" "One takes a vow to be a nun." "nun"中的"nun"匹配"One takes a vow to be a nun."
testString: 'assert(unRegex.test("One takes a vow to be a nun."), "Your regex unRegex should match "nun" in "One takes a vow to be a nun."");'
- text: 你的正则表达式unRegex应该匹配"bun" "She got fired from the hot dog stand for putting her hair in a bun." "bun"中的"bun" "She got fired from the hot dog stand for putting her hair in a bun."
testString: 'assert(unRegex.test("She got fired from the hot dog stand for putting her hair in a bun."), "Your regex unRegex should match "bun" in "She got fired from the hot dog stand for putting her hair in a bun."");'
- text: 您的正则表达式unRegex不应与"There is a bug in my code."匹配"There is a bug in my code."
testString: 'assert(!unRegex.test("There is a bug in my code."), "Your regex unRegex should not match "There is a bug in my code."");'
- text: 您的正则表达式unRegex不应该匹配"Catch me if you can."
testString: 'assert(!unRegex.test("Can me if you can."), "Your regex unRegex should not match "Catch me if you can."");'
```
