587d7db5367417b2b2512b97	Match Numbers and Letters of the Alphabet	1

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.

Tests

tests:
  - text: Your regex <code>myRegex</code> should match 17 items.
    testString: assert(result.length == 17, 'Your regex <code>myRegex</code> should match 17 items.');
  - text: Your regex <code>myRegex</code> should use the global flag.
    testString: assert(myRegex.flags.match(/g/).length == 1, 'Your regex <code>myRegex</code> should use the global flag.');
  - text: Your regex <code>myRegex</code> should use the case insensitive flag.
    testString: assert(myRegex.flags.match(/i/).length == 1, 'Your regex <code>myRegex</code> should use the case insensitive flag.');
