So what comes after Durandal? Rob Eisenberg talks to Carl and Richard about Aurelia! The conversation starts out focused on AngularJS and Rob's role with the open source project and ultimate departure. But that was back in November 2014 - what happens next? Aurelia is Rob's vision of what web developers need to build effective browser-based client applications. Rob talks about implementing Aurelia to utilize ECMAScript 6 and 7 while still polyfilling back to ES5 - the Javascript you recognize. This leads to a whole discussion on transpiling and how its possible to move a language forward without breaking backward compatibility, even a language as diverse as Javascript!
