Welcome our new ES5 overlords
summary
Claims that ES5 is broadly available and useful, demonstrated with concrete techniques: using Object.defineProperty to add non-enumerable methods so prototype extensions no longer break for-loops, prefixed extensions to avoid name collisions (examples of Chrome vs Sugar and Ember), an actual library called agave used in production since 2012, and a working live data→DOM demo built with prototype chain injection plus defineProperty that updates bindings and array pushes in real time.
