There are few javascript MVC frameworks as Backbone.js, SproutCore, Sammy.js, Spine.js, Cappuccino, Knockout.js, Javascript MVC, Angular.js and Batman.js. Same goes for template libraries: underscore.js, Jade, jQuery templates, mustache, dust.js, handlebars, Google Closure Templates. We'll discuss why such frameworks are needed and do a deep dive specifically into Ember.js and Handlebars.js. We where using Ember.js with Handlebars.js and less.js for frontend product development. We'll share our experience using these libraries and why we think they're critical when building a sufficiently complex frontend application.

The Scala programming language gives developers the safety of a modern, statically-typed, object/functional language, but with development speed and flexibility similar to that of dynamic languages. Play 2.0 is a new web application framework that harnesses the Scala language to enable you to create high-performance, scalable, modern web applications with ease. In this session, we'll dive in to play, walking through the framework and discussing our experience using it in production, including at FortyTwo. We'll also demonstrate how easy it is to get up and running with Play by creating a working demo app from scratch.
