Angular 2

Finally Angular2 has been released under beta version. It carries steep changes compared to version 1. Check Angular's version 2 documentation. Another reason for adopting angular 2 is performance.

Many improvements were done to improve memory usage and processing time. The digest cycle was replaced by the use of a change detection algorithm that walks the DOM tree. Other optimizations allow Angular 2 to detect precisely when the model has changed.

Having a performance way better than angular1 based on these benchmarks surely is an important factor for any project.
