Answer 1

You can't use a delay in the function, because then the change that you do to the element would not show up until you exit the function.

Use the setTimeout to run pieces of code at a later time:

var s = document.getElementById("div1");
for (i = 0; i < 10; i++) {

  // create a closure to preserve the value of "i"
  (function(i){

    window.setTimeout(function(){
      s.innerHTML = s.innerHTML + i.toString();
    }, i * 2000);

  }(i));

}
