freeCodeCamp Challenge Guide: Match Single Character with Multiple Possibilities

Match Single Character with Multiple Possibilities


Problem Explanation

Using the match() method, you can extract parts of a string that match with your regular expression. In this challenge, you are extracting the vowels “a, e, i, o, u” from a provided string.


Hints

Hint 1

Are you attempting to use the test() method? Remember this method only returns True or False – we need to extract the vowels from the string.

Hint 2

Have you tried using the ‘’ character case match without commas? i.e. [abcd] vs [a, b, c, d]
