javascript - Comparing array elements to character -

i'm trying write simple javascript program check if letter vowel. problem output incorrect , should " vowel."

javascript:

function findvowel(letter1, vowels) {     var count = vowels.length;     (var = 0; < count; i++) {         if (vowels[i] === letter1) {             var message1 = " vowel";             document.getelementbyid('exercise3').innerhtml = letter1 + message1;         } else {             var message2 = " consonant";             document.getelementbyid('exercise3').innerhtml = letter1 + message2;         }     } } 

html:

<script>     $(document).ready(function() {         findvowel("a",["a","e","i","o","u"]);     }); </script> 

output:

a consonant 

add break loop doesn't keep going.

function findvowel(letter1, vowels) {     var count = vowels.length;     (var = 0; < count; i++) {         if (vowels[i] === letter1) {             var message1 = " vowel";             document.getelementbyid('exercise3').innerhtml = letter1 + message1;             break;         } else {             var message2 = " consonant";             document.getelementbyid('exercise3').innerhtml = letter1 + message2;         }     } } 

you can use return false; stop function right away when vowel matched, in normal cases break used because there might other codes going on after loop.

btw:

function findvowel(letter){     //thanks p.s.w.g reminding me []     return letter+" "+(/[aeiou]/i.test(letter)?"vowel":"constant"); }
