Destroy an object after set time

I have been looking around for this but have turned up a blank

is it possible in javascript to create an instance of an object which has a set time to live, after which it would be destroyed?

a case would be where a item is added to an array every 5 seconds and shown in the visual, each item then should be removed after it have been in view for a minute. I hesitate to run a timeout function checking the array every second to clear them..

OOP FTW. Why not create some sort of self removing object?

function SelfRemover(){//constructor
};

SelfRemover.prototype.addTo = function(arr) {
   var me = this;
   arr.push(me); //adding current instance to array

   setTimeout(function() { //setting timeout to remove it later
       console.log("Time to die for " + me);
       arr.shift();
       console.log(arr);
   }, 60*1000)
}

Usage

var a = [];
setInterval(function(){new SelfRemover().addTo(a); console.log(a);}, 5*1000);
