    copied!<p>I have an array of halls like this, which I am getting from a $http.get(). </p> <pre><code>$scope.halls = [ { "_id": "524886d4c6d8a5a3b8949f6f", "alias": "", "hallId": "2", "locationHint": "Near support team", "name": "Conference Hall", "bookQueue": [], "occupancy": { "occupied": true, "occupiedBy": "Vignesh", "purpose": "Sync up", "team": "Edge", "timeRange": { "from": "2013-10-02T19:08:44.752Z", "to": "2013-10-02T19:08:44.752Z" } }, "capabilities": [ "ceiling mic", "room speaker", "projector", "Mac machine" ] }, { "_id": "524886fbc6d8a5a3b8949f70", "alias": "", "hallId": "3", "locationHint": "Near Edge Team", "name": "Training room", "bookQueue": [], "occupancy": { "occupied": true, "occupiedBy": "Tharma", "purpose": "Review", "team": "Platform", "timeRange": { "from": "2013-10-02T19:08:44.752Z", "to": "2013-10-02T19:08:44.752Z" } }, "capabilities": [ "ceiling mic", "room speaker", "projector" ] }, { "_id": "52488794c6d8a5a3b8949f71", "alias": "", "hallId": "4", "locationHint": "Near front office", "name": "Front Office Discussion room", "bookQueue": [], "occupancy": { "occupied": false, "occupiedBy": "", "purpose": "", "team": "", "timeRange": { "from": "2013-10-02T19:08:44.752Z", "to": "2013-10-02T19:08:44.752Z" } }, "capabilities": [ "ceiling mic", "room speaker", "TV" ] } ] </code></pre> <p>I want to update the <code>hall.occupancy</code>, when the current date ( <code>Date.now()</code> )is greater than <code>hall.occupancy.timeRange.to</code> . In this case, I am not going to watch <code>hall.occupancy.timeRange.to</code> because, it is not the property that is going to change. Is there an angular way to do this, because it would get really messy to put a <code>setInterval</code>. </p> <p>I am not really sure on how to go about this. </p> <p>I am still in the early stages of learning angular, so it would be good if you were gentle in pointing out an efficient way. </p>
