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

Regarding your code, your if condition needs no i2

if('aouie'.search(a[i]) > -1){ 

I wonder, why all that use of arrays and nested loops, the below regex could do it better,

var str = "run forest, run";
var matches = str.match(/[aeiou]/gi);
    var count = matches ? matches.length : 0;
    alert(count + " vowel(s)");
