// Exercise 2 - Closures
// Wrap the following code in a closure and export only the "countdown" function.

// Code
(function (win, name) {
  var index;

  function log(){
    console.log(index);
  }

  function iterate(){
    log();
    if(index>1) setTimeout(iterate, 1000);
    index--;
  }

  function countdown(){
    index = 10;
    iterate();
  }
  win[name]= countdown;

})(this, 'countdown')
