how to set a timeout on an array element

function ArrayPlusDelay(array, delegate, delay) {
  var i = 0
  
   // seed first call and store interval (to clear later)
  var interval = setInterval(function() {
    	// each loop, call passed in function
      delegate(array[i]);
      
        // increment, and if we're past array, clear interval
      if (i++ >= array.length - 1)
          clearInterval(interval);
  }, delay)
  
}

ArrayPlusDelay(['x','y','z'], function(obj) {console.log(obj)},1000)
