(function () {

var showText = function(target, msg, index, interval){

  var el = document.getElementById(target);

  if(index < msg.length){
    el.innerHTML = el.innerHTML + msg.charAt(index);
    index = index + 1;
    setTimeout(function(){
      showText(target,msg,index,interval);
    },interval);
  }

};


showText("id", "Hello, World!", 0, 50);   

})();

you could improve on this code by changing it so you only get the el one time due to the fact that it takes a bit of resources to modify the DOM.
