• Native promises browser support on Can I Use. Only possible concern is using the catch on older versions of IE. You can get around this by using strings to call catch, like : somePromise['catch'](function...)
• Question from Nick Makey: Are Native Promises A+ compliant? I still had trouble finding a definitive answer but the polyfill I mentioned in the talk is a subset of RSVP.js which is compliant. Additionally there is a native promises only polyfill that is also A+ compliant. I believe that should cover most cases.
• Another question from Nick Makey: What’s wrong with Jquery Promises Exactly? I didn’t have a really detailed answer in the talk, but this post gives a good rundown and several examples.
