Angular Vs. Angular JS – What Should You Prefer for Your Project Development

The rise of modern browsers and network technologies has resulted in massive digital disruption.Companies today are creating applications for the ‘mobile-first’ world across all platforms. In order to reach out to target customers, web or mobile apps development projects are being preferred as compared to physical offices. This shift has translated in the better adoption of front–end development. In line with this, there exist many platforms for web development today. The plan should be to pick the right one.

What is Angular and Angular JS?

Designed by Google and first launched in 2009, Angular JS has become one of the most popular JavaScript frameworks so far as it is easy to use, provides high simplification to the entire development process as well as supports the latest standards of JavaScript (ES6). Over the years, it has become one of the most refined frameworks to create web and mobile apps which are both modular as well as responsive. 

AngularJS development services are widely acclaimed and are extensively used to simplify the development process. Generally, it is an open source development framework that effectively addresses the challenges of web development and assures the provision of interpreted web & mobile app development by integrating simple HTML codes. 

Angular, on the other hand, is a comprehensive term that is used for all the versions, which got launched after AngularJS (Angular 1), including version from Angular 2 to Angular 10. Angular is based on TypeScript – a superset of ES6 with lambda operators, iterators or reflection’s mechanism, whereas AngularJS is based on JavaScript.

Angular vs AngularJS

Angular JS development services and Angular development services differ in their basic components. The TypeScript that is used by Angular is a superset of ES6, which has backward compatibility with ES5. 

For an Angular JS web development company, the JavaScript-based framework is dependent on terms of scope and controllers. On the other hand, Angular development services depend on the hierarchy of components. In simple terms, it can be inferred that Angular is component-based while AngularJS is directive-based.

When a business hires Angular JS developers, he needs to be adept at JavaScript and a stickler for following directives. While both Angular and AngularJS use Directives, the manner in which they are used makes all the difference. Angular has a set of standard Directives while AngularJS has a pack of them. One has to be cautious while using the Directives. 

Difference in Architectures of Angular and AngularJS

Angular JS

The Angular JS framework has a model-view-controller (MVC) architecture that acts as the central component as it manages data, logic, rules, and directs how the applications will behave.The MVC components act in the following manner:

  • Model: The model is where all the data is stored and managed from.
  • View: The view generates an output after reviewing the information contained in the model.
  • Controller: The controller receives the input and converts it to commands which it then sends to the model and view.


Angular uses components that are directives along with templates. Angular comprises two kinds of directives:

  • Structural directives: the Structural Directives alter the DOM’s layout by replacing its elements.
  • Attributive directives: the Attributes Directives change the way the DOM behaves as well as the appearance of the element.

Apart from these two intrinsic differences, the following architectural differences also occur between the two:

  1. Mobile support: AngularJS does not provide mobile support while Angular supports mobile.
  1. Performance and Speed: The two-way binding feature ultimately reduces the efforts and time of construction for an Angular JS web development company. In case of Angular, the framework upgrades to a better structure, which in turn provides improved performance and speed.
  1. Tool support: Angular JS framework relies on third-party tools such as IDE and WebStorm, whereas, Angular uses the Command Line Interface (CLI) to reduce the time when creating applications.

The advantages of Angular over AngularJS

The advantages of Angular over AngularJS

1. Modularity

Most of Angular’s core functionality has been incorporated by various modules. This has resulted in the creation of a lighter and a faster core.

2. Dynamic Loading

There is a combination of asynchronous templates and added support for reactive programming in case of Angular. This functionality is absent for Angular JS.

3. AOT/Ahead-of-Time

The popular Angular compilation helps convert the HTML and TypeScript into JavaScript during the build time process. AOT compiles the code and the browser loads the compiled code to produce faster rendering.

4. CLI

Command Line Interface helps create and serve angular applications in a better manner. This feature not only takes care of project building, but also makes testing more accessible.

5. The Architectural Component

Angular boasts of very well-defined and divided functional and logical components.

6. Dependency Injection

Angular uses unidirectional change detection. Rather than using directives the way they are used in case of AngularJS, Angular makes use of Hierarchical Dependency Injection to boost the framework’s performance significantly.

7. Language Options

Although Angular is written in TypeScript, it also offers other language choices such as ES5, ES6, and Dart. These are popular coding languages which are most widely used.

8. Routing

The Angular framework has a simple path. It can interpret a URL as a directive to navigate to a client-view which is of a great advantage to the developer community.

1. MVC Model

The Model View Controller model makes use of data binding to speed up application development. The use of two-way data binding helps provide a conclusive interface that enables the developer community to use less code in the projects.

2. Testing Made Easier

AngularJS comes pre-equipped with a ready unit testing feature that is continuously updated. A developer can make use of his own code to ensure that there are no defects in his design.

3. Comprehensive Solution

AngularJS offers a comprehensive solution for frontend development since it does not depend on other frameworks and plugins.

4. Use of HTML

Since the declarative language AngularJS uses is HTML, therefore, it is quite intuitive.

5. Simpler Architecture

The AngularJS framework provides the users with reusable components. It has a much simpler architecture that aids quick development of mobile and web applications.  

Angular and Angular JS have their differences, but despite these differences, they also have their unique positives. Both the frameworks are maintained by Google, thus, they both have an extensive support of the developer community. Angular is preferred in cases where the user desires to create dynamic applications for web or mobile while Angular JS is preferred when creating single page applications using HTML. 

It is essential for any business to go through the positives and negatives of either platform before making a choice of framework to be used for its web or mobile application development.
