Counting vowels in javascript

Question

I use this code to search and count vowels in the string,

a = \"run forest, run\";
a = a.split(\" \");
var syl = 0;
for (var i = 0; i < a.length - 1; i++) {
         


        

Answer 1

You can use the .match to compare a string to a regular expression. g is global which will run through the entire string. i makes the string readable as upper and lower case.

function getVowels(str) {
      var m = str.match(/[aeiou]/gi);
      return m === null ? 0 : m.length;
    }
