SetTimeout with standard counter

Question

I want to create a alert \"Hello\" which will show up after 10sec. I used setTimeout and it working fine. Now i would like to do counter(timer) which will show 10, 9, 8,7 ...

Answer 1

You can do something like that:

var count = 10; 
var timer = function(){
  setTimeout(function(){
    alert(count);
    if(count == 0){
      //do something
    }
    else{
      count--;
      timer();
    }
  }, 1000);
}

To run just:

timer();
