Match Numbers and Letters of the Alphabet

Match Numbers and Letters of the Alphabet

---

Problem Explanation

In this challenge, you are asked to return a collection of both numbers and letters extracted from a string. Our goal is to create a single regexp that captures the range of letters between h and s, and the numbers from 2 to 6.

---

Hints

Hint 1

Are you using the match() method? If so, then are you calling the method from the appropriate variable? i.e.

let input_string = "The string you are testing on";
let yourRegExp = /[h-s]/;
let correct_result = input_string.match(yourRegExp); // passes - returns characters H to S

let incorrect_result = yourRegExp.match(input_string); // fails - .match() is not a function

Hint 2

Did you remember to enable the regexp flags such as "i" for ignoring case and "g" for retreiving multiple values? If so, then are you including both the character case match for numbers AND letters?

let regexp = /[a-z1-100]/gi;
// above code returns all characters from A to Z, along with all numbers from 1 to 100
// this includes the letter A and Z and the numbers 1 and 100
