Why Angular 2.0?

Hi Friends,

In this section, we’ll talk about Angular’s upcoming version Angular2. We will discuss major changes around Angular 2 and what to expect from this version.

Angular is currently the most popular off-course. The Angular team devised a way to allow projects to run both Angular 1.X and 2.0 code at the same time. Upgrading could now be a gradual process. In my view, this saved the framework from almost certain stagnation and the horror of thousands of challenging to maintain, legacy code bases.

What you should expect from 2.0?

There are many things which you can expect from this release. This framework is undergoing the largest change between versions by far.

Development on Angular 2.0 emphasizes removing the framework’s unnecessary complexity. They removed and replaced directives, controllers, modules, scopes and nearly every other concept from version 1.X. What’s left is a framework that uses features of ES-5 and ES-6 to the fullest and makes different design decisions that the team hopes will make the framework easier to learn.

Beyond the focus on making the framework simpler, there are several other notable goals for version 2.0:

Performance improvements
Native app support
Server-side rendering

These changes are huge for Angular and would have been challenging to build with 1.X. Let’s delve inside!

Performance

Improving performance was one of the top items on anyone’s wish list for Angular’s next version. If you’ve worked enough with Angular, you’ve hit points where the simple implementation breaks down and start experiencing slowness.

During every digest cycle, the framework checks if any of hundreds or thousands of values in your app changed. one-way data flow and immutable data. By embracing these, Angular now only updates once the data changes. Detecting change becomes a quick check of an object’s reference and not all its values.

Native Apps

Creating native apps using Angular is a big advancement planned on the roadmap for 2.0. It looks as though they are building 2.0’s native app rendering using React Native. This will usher in a new generation of hybrid apps that perform like native but share logic across multiple platforms.

Server-Side Rendering

Another long requested feature for Angular is the ability to render on the server. Server-side rendering speeds up initial page load times and improves performance. Seeing pages render faster is going to greatly improve the feel of the next generation of web apps written in Angular.

Who should use Angular?

Angular will likely maintain as the most popular client side framework for quite some time. This makes it a safe choice for anyone starting a new project. 2.0 represents a gigantic shift from the first version of Angular.

Angular 2.0 is written in TypeScript, a programming language from Microsoft that adds type checking and other enhancements to JavaScript. In fact, in a recent poll of its community, the largest group of developers said they too would be using TypeScript. I would say this way Angular 2 is a lethal combination of Google and Microsoft together.

I hope you would have liked this discussion. Thanks for Joining me.

Thanks,

  1. Excellent summary article, Rahul. I’ve been on the fence on what JS script/library to learn for a very long time.

    I’m a C#/ASP.NET web dev, and after playing with Angular2 + TypeScript it felt very natural. I love its simplicity. Can’t wait to continue this adventure.

  2. Hi, I start study Angular from one week, and I use it on a small web site, and it’s greate but now I would like to start to use for more projects, do you think I have to start with angular 2 or continue to use angular 1 ore wait for angular 2 release ?
    thanks

    • yeah wait for stable release for angular 2, If you would like to start with Angular 2. Otherwise, there is no problem with Angular 1. Also, Google will be releasing migration path as well in case if you want to switch to angular 2.
