    Holy cow! I totally did one of these without even looking at this post.
    Code:
    function findType(chara){
    var vowels=new Array();
    vowels[0]='a';
    vowels[1]='e';
    vowels[2]='i';
    vowels[3]='o';
    vowels[4]='u';
    vowels[5]='y';
    for(i=0;i<6;i++){
    if(chara==vowels[i]){
    alert('Vowel present.');
    }
    }
    }

    Well he's still not said what it is he wants, however:

    Code:
    function isVowel(chara)
    {
    	// Checks if the first character is a vowel
    	// If the string is longer than 1 it makes no difference
    	// Case insensitive
    	return chara.test(/^[aeiou]/i);
    }

    }
    Code:
    return /[aeiou]/i.test( chara );

    Code:
    String.prototype.isVowel = function () {return /[aeiou]/i.test(this) || (Math.random() > 0.5 && /y/i.test (this))}
    
    alert ('y'.isVowel());
