Airbnb has tons of things that would be impossible (or annoying to use) without JS: search by map, sliders, availability calendars, price calculation, credit card tokenization, etc. Here is a recent talk where they explain how they solved some tricky UX problem by using a "modern" JS framework such as React.js http://www.infoq.com/presentations/airbnb-resolution-center http://www.infoq.com/presentations/airbnb-resolution-center In this other talk they also explain how (and why) they evolved from vanilla Rails (i.e. more static HTML) + jQuery, to Backbone, and finally to isomorphic React.js https://www.youtube.com/watch?v=gMvvb6F8dgk https://www.youtube.com/watch?v=gMvvb6F8dgk
