# --description--
|
|
|
|
Using the hyphen (`-`) to match a range of characters is not limited to letters. It also works to match a range of numbers.
|
|
|
|
For example, `/[0-5]/` matches any number between `0` and `5`, including the `0` and `5`.
|
|
|
|
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);
|
|
```
|
|
|
|
# --instructions--
|
|
|
|
Create a single regex that matches a range of letters between `h` and `s`, and a range of numbers between `2` and `6`. Remember to include the appropriate flags in the regex.
|
|
|
|
# --hints--
|
|
|
|
Your regex `myRegex` should match 17 items.
|
|
|
|
```js
|
|
assert(result.length == 17);
|
|
```
|
|
|
|
Your regex `myRegex` should use the global flag.
|
|
|
|
```js
|
|
assert(myRegex.flags.match(/g/).length == 1);
|
|
```
|
|
|
|
Your regex `myRegex` should use the case insensitive flag.
|
|
|
|
```js
|
|
assert(myRegex.flags.match(/i/).length == 1);
|
|
```
