| ## Description
 | ||
| <section id="description">使用连字符( <code>-</code> )匹配一系列字符不仅限于字母。它也适用于匹配一系列数字。例如, <code>/[0-5]/</code>匹配<code>0</code>到<code>5</code>之间的任何数字,包括<code>0</code>和<code>5</code> 。此外,可以在单个字符集中组合一系列字母和数字。 <blockquote>让jennyStr =“Jenny8675309”; <br>让myRegex = / [a-z0-9] / ig; <br> //匹配jennyStr中的所有字母和数字<br> jennyStr.match(myRegex); </blockquote></section>
 | ||
| 
 | ||
| ## Instructions
 | ||
| <section id="instructions">创建一个与<code>h</code>和<code>s</code>之间的字母范围匹配的正则表达式,以及介于<code>2</code>和<code>6</code>之间的数字范围。请记住在正则表达式中包含适当的标志。 </section>
