countVowels

+

Retuns number of vowels in provided string.

+

Use a regular expression to count number of vowels (A, E, I, O, U) in a string.

+
const countVowels = str =>
+  return (str.match(/[aeiou]/ig) || []).length;
+// countVowels('foobar') -> 3
+// countVowels('gym') -> 0
+

escapeRegExp

Escapes a string to use in a regular expression.

Use replace() to escape special characters.
