The journey started around 2009 and its 2019, so the framework survived for a decade which shows that it’s a very successful product given by Google, but the huge success comes with a great responsibility to maintain and upgrade it for future concern. By the time, from AngularJs, the Angular team has decided to revamp it completely and make a sustainable product, hence the newly created structure called Angular 2 which is the completely re-written of the AngularJs framework.
What is the difference between AngularJS and Angular?
Angular is one of the widely used web frameworks developed by Google, its bean a year now and people are using and upgrading their projects into the Angular. The journey started around 2009 and its 2019, so the framework survived for a decade which shows that it’s a very successful product given by Google, but the huge success comes with a great responsibility to maintain and upgrade it for future concern. By the time, from AngularJs, the Angular team has decided to revamp it completely and make a sustainable product, hence the newly created structure called Angular 2 which is the completely re-written of the AngularJs framework. Still, people are confused between both words like AngularJs and Angular and it may be confusing for the audience as well. There are certain differences between them because Angular 2+ is completely re-written over AngularJs, so let’s see a few important differences which are listed below.
We need to keep in mind the exact ng directive in order to bind the property in AngularJs, but in Angular 2+ we have () bracket for event binding and  brackets for the property binding.
An application written using Angular 2+ will be compatible with the future version of the Angular like Angular 4, 5,6,7,8 and so on.
AngularJS supports MVC (Model View Controller) pattern which uses model properties and uses it into the view, while Angular 2+ uses directive and component and the component values can be used into the template in order to render and HTML.
AngularJS comes with the model-based architecture where we can reduce development time and efforts. But Angular 2+ comes with great features like renderer engine and dependency injection mechanism, this we will be able to get a higher performance to compare to AngularJs. Recently Angular 9 going to release soon which comes with the Ivy renderer engine which turns Angular application much faster.
Basically, AngularJS does not provide any kind of mobile support, while Angular 2+ provides mobile support and desktop application support as well.
Dependency injection is the wide spreader term, this AngularJS does not support the dependency injection while Angular 2+ supports dependency injection. It is used to inject the outer dependency into the component in Angulars like accessing the service methods of the service class to interact with the API and its responses.
As we can see, above are the few major difference between AngularJs and Angular thus there are other various differences which also differentiates its usage. For example, AngularJS is no more updated thus in the future there will not be any support from the framework and while in Angular, new semantic versioning is there so that we can upgrade to the latest version by just following the few steps. One of the major differences between two of them is that AngularJs runs only at the client side but at the same time, Angular 2+ runs on both platforms like client-side and server-side as well which makes it Angular popular for the developers around the globe. As a developer, the code reusability is matters a lot while in AngularJs we don’t have flexibility for code reusability a lot but in Angular, everything is a component which is a kind of directive, we can create as much as components we need so that it can be pretty easy to maintain the structure as well as code re-usability widely.
In this article, we have gone through the difference between the AngularJs and Angular which shows how we can pick any of them and can start digging into it. Well, Angular 2+ is completely re-written so people who are new and don’t know about AngularJS can easily pick up Angular 2+ because it is going to put much impact in world of application development for upcoming years, so choose your Angular wisely and be a proof it, I hope you have enjoyed this guide, Keep reading.
