The talks at FutureJS were consistently fantastic. I highly recommend all of them. A good starting place would be A Conceptual Future For The Multi-Device Web, which covered a plethora of new APIs like WebRTC, Geolocation, and Orientation, combining them in rather novel ways. Also excellent was Invent The Future, Don't Recreate The Past, which looked at the evolution of JS and possible future consequences of the decisions being made in ES6 and ES7. Overall, fantastic conf with excellent speakers (Jeremy Ashkenas, Reginald Braithwaite, and David Nolen, to name a few personal heroes). http://futurejs.org http://futurejs.org
