deixe hugStr = "Bear hug";
vamos huRegex = /hu./;
humStr.match (huRegex); // Retorna ["hum"]
hugStr.match (huRegex); // Retorna ["abraço"]

unRegex para que ele corresponda às strings "run" , "sun" , "fun" , "pun" , "nun" e "bun" . Seu regex deve usar o caractere curinga. Tests
tests:
- text: Você deve usar o método <code>.test()</code> .
testString: 'assert(code.match(/\.test\(.*\)/), "You should use the <code>.test()</code> method.");'
- text: Você deve usar o caractere curinga em seu regex <code>unRegex</code>
testString: 'assert(/\./.test(unRegex.source), "You should use the wildcard character in your regex <code>unRegex</code>");'
- text: Seu regex <code>unRegex</code> deve combinar <code>"run"</code> em <code>"Let us go on a run."</code>
testString: 'assert(unRegex.test("Let us go on a run."), "Your regex <code>unRegex</code> should match <code>"run"</code> in <code>"Let us go on a run."</code>");'
- text: Seu regex <code>unRegex</code> deve combinar <code>"sun"</code> em <code>"The sun is out today."</code>
testString: 'assert(unRegex.test("The sun is out today."), "Your regex <code>unRegex</code> should match <code>"sun"</code> in <code>"The sun is out today."</code>");'
- text: Seu regex <code>unRegex</code> deve combinar <code>"fun"</code> em <code>"Coding is a lot of fun."</code>
testString: 'assert(unRegex.test("Coding is a lot of fun."), "Your regex <code>unRegex</code> should match <code>"fun"</code> in <code>"Coding is a lot of fun."</code>");'
- text: Seu regex <code>unRegex</code> deve combinar <code>"pun"</code> em <code>"Seven days without a pun makes one weak."</code>
