## Description
<section id='description'>
Using the hyphen (<code>-</code>) to match a range of characters is not limited to letters. It also works to match a range of numbers.
For example, <code>/[0-5]/</code> matches any number between <code>0</code> and <code>5</code>, including the <code>0</code> and <code>5</code>.
Also, it is possible to combine a range of letters and numbers in a single character set.

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