Now, coming to present times…
In 2017, however, if you are looking to create a dynamic web app, then, by all means, you will opt for a company providing Angular2 development services.
Angular 2? Really?
The programming community is embracing Angular2 as a new blessing. If you have a closer look at both, then you will not be able to mark Angular2 as a true successor of its previous generation.
On the contrary, Angular2 now caters to the ES6 specifications courtesy it’s completely new Typescript. In this respect, this second generation also brings along considerable modifications and changes in package libraries which seem to facilitate coding significantly.
AngularJS vs Angular2
Let’s have a look at some of the primary differences between the two prior to going into details.
Spoilt for choices
It is perhaps one of the biggest differences that you will enjoy with Angular2. Choose from TypeScript, ES5, ES6 or Dart – Angular2 has them all. The introduction of TypeScript is a big boost to the coding community as it prevents multiple rewriting of codes.
The Responsive Edge
What’s a website without its mobile iteration nowadays? Angular 1.x did not come with the mobile development phase as a part. If you, as a newbie, are dumbstruck by this fact, then remember:
AngularJS 1.x came at a time when smartphones had not made their worthy presence in the global market. So, having mobile site was an out of the box idea with all AngularJS development services.
Components for Controllers
While Angular 1.x pondered extensively on the use of $scope and controllers, with Angular2, you can effectively deploy components in the design of your dynamic web apps.
So, how does this benefit?
Components come in the form of bundles in the raw text. This means that you will be able to incorporate methods and class libraries in the web app dynamically without the need of stalling your work now and then.
The setup fight
It is one segment when Angular 1.x takes a slight edge. Ask all Angular2 development services and they will tell that Angular 1.x is a lot easier to customize and setup. This is because in the first iteration, you only require the reference of the concerned library before proceeding to subsequent phases.
On the other hand, Angular2 will project its dependency on other subsequent libraries, thus lengthening the configuration process.
Bootstrap and directives
While bootstrap options in AngularJS were available both in attribute and code formats, Angular2 gives way to bootstrap setups and embraces coding as the sole option.
If you consider changes in structure directives, you will find ng-repeat giving way to ngFor in Angular2.
Now, it is time to dig deeper into the major differences between these two development frameworks.
Highlighting dependency injection
One thing that you will have to agree with is the improved dependency injection of Angular2. This allows a greater deal of opportunities and customization while coding with an object-based framework. Now, as you know, a dependency injection will consist of three segments.
- The injector, as the name suggests, finds use in injecting the dependencies
- Bindings through which you name each dependency uniquely
- Creation of actual dependencies
Now, this is where AngularJS development services lose out thus giving the development edge to Angular2.
The benefits of ECMAScript
Perhaps what will stand out as the biggest USP for you is the availability of extensive inheritance in ECMAScript. Now, instead of limiting developments to a prototype, you will be able to call super perimeters to the constructors of the parent class.
The above comparison clearly shows that while Angular2 is at an edge over its elder sibling, the former is still not out of the game completely.
Recently on its official blog, the team declared that AngularJS is planning one more significant release, version 1.7, and on July 1, 2018 it will enter a 3 year Long Term Support period that is till July 2021.
