ES6 and Angular 2.0 – What’s New?
- That’s because the first thing developers should know about Angular 2.0 is that there is no upgrade path from Angular 1.
- With that in mind, developers should find Angular 2.0 a good place to develop responsive and mobile-ready applications.
- For practical purposes, Angular 2.0 should probably be best thought of as an entirely new framework rather than an “upgrade” to Angular 1.
- x for now until Angular 2.0 brings a large enough advantage that switching would be beneficial.
- x but run the risk of being left behind as 2.0 matures, or take advantage of the speed and new features of Angular 2.0 but possibly be stuck if adoption isn’t widespread and Angular 2.0 stops being updated?

What’s new in Angular 2.0 makes for a difficult question. A better way to pose the question may be, “What’s different in Angular 2.0?” That’s because the first thing developers should know about Angular 2.0 is that there is no upgrade path from Angular 1.x– Angular 2.0 is a completely new framework.
What is Angular?
AngularJS is, of course, the popular open-source framework for building rich web applications. According to libscore.com, AngularJS is being used by over 12,000 of the top million websites as of Libscore’s May 2016 data.
The Angular 2.0 team took a mobile-first strategy with the belief that making sites fast and flexible for mobile was a harder problem than writing for desktop. With that in mind, developers should find Angular 2.0 a good place to develop responsive and mobile-ready applications. The Angular team also chose to focus on so-called “evergreen” browsers that update automatically. These include newer versions of:
Notably, Angular 2.0 supports Internet Explorer 9, which is not an evergreen browser. More details are available here. The limited browser support means that developers need fewer workarounds to support older, troublesome browsers. The downside is that some users are still using older browsers, and those users won’t be able to use applications written in Angular 2.0.
