I'm trying to convert numbers into letters. I'm making an array of divs that either need a number or a number and letter. so 1-3 are just 1-3. but 4-13 need to be a/4, b/5, c6 and so on. is there a way I can converts these numbers into letter easily. maybe changing the ascii values by a set amount?

     for(var i = 1; i < 33; i++){

    if( i < 4 || (i > 13 && i < 20) || i > 29){

        $('#teeth-diagram').append(<div class='tooth' id=' + i + '>&nbsp;</div>);

    }else{

        $('#teeth-diagram').append(<div class='tooth' id=' + Letter goes here + / + i + '>&nbsp;</div>);

    }

}

since 97 is the ascii value for 'a', and your value for 'a' is 3, you need to do this to get the value of the integer converted to a character:

if(i>=3){

    String.fromCharCode(94 + i);

}
