Hi, use this piece of code:

var contador = 0;
var strInput = prompt("Please enter a few words:", "")
indice = strInput.indexOf("i");
while (indice!=-1) {
  contador++;
  indice = strInput.indexOf("i",indice+1);
}
document.write("there are " + contador + " instances of the letter \'i\' in 
your string.");


Regards,

Federico García
