Can we make timer in alert using javascript?

i want to make an alert that have timer in it,
the alert will show this message:

Please wait to process data 3 second..

Please wait to process data 2 second..

Please wait to process data 1 second..

and if the timer is done, the text will change to
Succesfully process data..

I tried this one

    function countdown() {
    var seconds = 3;
    function tick() {
        var counter = document.getElementById("counter");
        seconds--;
        counter.innerHTML = "Please wait to process data " + String(seconds)+ " Second";
        if( seconds > 0 ) {
            setTimeout(tick, 1000);
        } else {
            alert("Succesfully process data");
        }
    }
    tick();
}

countdown();

<div id="results"></div>
<button id="stop">Stop</button>

but this code will show the timer in div not in alert, i tried to edit to make it show in alert but still can not figure it out, can you guys help me?
