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dotperiod 。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""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""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\(.*\)/)); - text: 您应该在正则表达式unRegex使用通配符 testString: assert(/\./.test(unRegex.source)); - 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.")); - 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.")); - 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.")); - 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.")); - 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.")); - 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.")); - 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.")); - 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.")); ```
