使用连字符(-)匹配字符范围并不仅限于字母。它还可以匹配一系列数字。

例如,/[0-5]/匹配05之间的任意数字,包含05

此外,还可以在单个字符集中组合一系列字母和数字。

let jennyStr = "Jenny8675309";
let myRegex = /[a-z0-9]/ig;
// matches all letters and numbers in jennyStr
jennyStr.match(myRegex);

--instructions--

创建一个正则表达式,使其可以匹配hs之间的一系列字母,以及26之间的一系列数字。请记得在正则表达式中包含恰当的标志。

--hints--

你的正则表达式myRegex应该匹配 17 项。

assert(result.length == 17);

你的正则表达式myRegex应该使用全局标志。

assert(myRegex.flags.match(/g/).length == 1);

你的正则表达式myRegex应该使用忽略大小写的标志。

assert(myRegex.flags.match(/i/).length == 1);
