Angular web development: How it is different from AngularJS?
Angular evolved from AngularJS version 1.0 to Angular 2.0 and Angular 4.0 in 5 years. Let’s learn
how angular web development is different from AngularJS development.

AngularJS was developed by Google in 2009 and version 1.0 was released in 2012. Since then, Angular
has ruled the world of open-source JavaScript frameworks, with widespread adoption among
companies and programmers so much so that Angular web development remains the preferred choice
for building a high-performance web app or a mobile app.

Understanding the different versions of Angular
Angular includes version 2 and version 4. Here is how Angular is different from AngularJS.
Architecture
AngularJS has an architecture that is based on model-view-controller (MVC) design. The model is the
central component responsible for expressing the behavior of the application, along with managing its
data, logic and rules. The view creates an output based on the information that is there in the model.
The controller receives the input, converts it into the commands and sends these commands to the
model and the view.

The controller receives the input, converts it into the commands and sends these commands to the

In Angular 2, components and directives replaced the controllers and $scope. Components, which are
the directives with a template, deal with the application’s view and logic on the page. Angular 2 comes
with two types of directives – structural directives that change the DOM’s layout by removing and
replacing its elements, and attributive directives that alter the appearance and behavior of a DOM
element.

Language
AngularJS is written in JavaScript.
Angular web development uses Microsoft’s TypeScript language. It is a superset of ECMAScript 6
(ES6), and it offers combined benefits of the TypeScript features, such as type declarations, along with
the advantages of ES6, like lambdas and iterators.

Angular 4 is compatible with the latest versions of TypeScript that have powerful object-oriented and
type checking features.

Expression syntax
In AngularJS, the right ng directive is necessary to bind an image, property or an event. On the
contrary, Angular focuses on [ ] for property binding and ( ) for event binding.

Mobile support
AngularJS was not developed with mobile support, but Angular 2 and Angular 4 both offer mobile
support.
Performance
AngularJS was originally made for designers, not developers. Although some evolutionary
enhancements were made in the design, they did not meet the requirements of the developers. The later
versions – Angular 2 and Angular 4 – have been upgraded to provide improved performance.

Speed
Features like two-way data binding helped AngularJS to reduce the development time and effort.
Angular 2 provides a structure for easy development and maintenance of big applications. The fastest
version until now is Angular 4.

Dependency injection
Angular uses unidirectional tree-based change detection and hierarchical dependency injection system,
which improves the framework’s performance.

Advantages of Angular
Angular web development is quick
It is mobile-oriented
TypeScript allows code optimization using OOPS concepts
It offers simple routing
It comes with a modularized animation package
Full TypeScript support leads to easy development of bulky applications
Advantages of AngularJS
It simplifies unit testing
Its MVC data binding helps in quick app development
Using HTML as a declarative language makes it intuitive
It is a complete front-end development solution as it does not require any frameworks or plugins
AngularJS apps can run efficiently on iOS and Android platforms
To sum up, each version of Angular has its own benefits. Angular is faster compared to AngularJS,
has a mobile-oriented approach and allows smoother migration from its earlier versions.
