Question

I am playing around with “ID’s” trying to get comfortable and such. I know jQuery has a really quick solution, but I want to know how to do it via js.

     var startTimer = function init(){
                var n = 0;
                var e = document.getElementById("output");
                var myTimer = setInterval (function() {e.innerHTML = n++;},100);
                // clearInterval(myTimer);
                if(myTimer === 10){
                    clearInterval(myTimer);
                    return;

                }
            }                  

           startTimer();

Did you actually want this?

function initTimer(){
    var n = 0;
    var e = document.getElementById("output");
    var timerid = setInterval( function() {
        e.innerHTML = n;
        if (n < 10) // count until ten
            n++;
        else
            clearInterval(timerid); // this happens somewhen later
    }, 100);
}
