--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.

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.

assert(result.length == 17);

Your regex myRegex should use the global flag.

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

Your regex myRegex should use the case insensitive flag.

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

let quoteSample = "Blueberry 3.141592653s are delicious.";
let myRegex = /change/; // Change this line
let result = myRegex; // Change this line

--solutions--

let quoteSample = "Blueberry 3.141592653s are delicious.";
let myRegex = /[h-s2-6]/gi; // Change this line
let result = quoteSample.match(myRegex); // Change this line
