+    // Note that ^ in Regex means "all characters not in the set", so placing it in front of aeiou means "Match everything that isn't a vowel"
+    // Enclosing a set in [] means that our string matches any individual character in that set
+    // Ending with our /g tag signifies that we want to do a global search and lets our engine know to going through the entire string.
