DOM events, timers, and XMLHttpRequests are some of the sources of concurrency commonly encountered by webapp developers. In JavaScript we typically deal with this concurrency by using asynchronous callbacks. Unfortunately this approach is verbose, obscures control flow, and breaks composability. In this talk I'll give an overview of Stratified JavaScript, a language extension which adds high-level concurrency features to JavaScript to help developers with choreographing concurrency in a more structured and natural way. I'll also demo Oni Apollo, which is our compact cross-browser, MIT-licensed Stratified JavaScript runtime.
