Angular vs. AngularJS: What You Need To Know

Angular vs. AngularJS: What You Need To Know

Web Development

Angular vs AngularJS

Due to our extensive custom development portfolio that includes multiple technologies both new and established, we get requests from multiple clients about the kind of technologies we can use and what is the difference between multiple technologies that sometimes overlap or at least the clients think that overlap. One of the key questions that come up every now and then with some frequency is the difference between AngularJS vs Angular. 

It’s a valid question as both are quite similar. AngularJs is the updated version of Angular but with some major upgrades and differences that makes selecting between both a slightly difficult choice.

What is Angular?

Angular is an open-source web app framework developed by the Angular team at Google. 

What is AngularJS?

It is an open-source and Javascript-based framework largely used for single-page web applications

Introduction to Angular 

Angular is a robust framework that utilizes typescript and HTML for building single-page applications. Functionalities that may be optional or critical are imported into the app as libraries.

There are some key components of an Angular app architecture. Various components are then arranged as Ngmodules. The code is then arranged as a functional set and compiled. 

Angular apps will have a root module named AppModule that is used as the bootstrap for the initial app launch. And then, NgModule imports functions from other modules for other auxiliary tasks and responds to user requests. The functionalities of various Ng Modules can be used by other modules which makes them interchangeable and usable. 

One of the advantages of using distinct modules is that you can divide the functionalities into distinct modules. This can help in managing and building large applications. You can also load codes selectively and on-demand to lower the overall code loaded during startup and reduce response time and make the overall app faster. 

Also, Angular uses components that can be connected with the Root component for the component hierarchy and with the DOM that is Document Object Model which defines the view to be displayed for the end user.

Introduction to AngularJs

AngularJS is a Javascript framework that utilises Javascript over typescript by Angular. It was developed by Google and an army of volunteers maintains and updates this open-source single-page web app location framework. Angular JS utilises both MVC that is Model View & Controller and Model View-View Model architecture. AngularJs has become the preferred choice for front-end MEAN stack developers.

Key Features of Angular

Here are some of the major features or advantages of Angular:

Data Binding

With Angular, you can use data binding to move javascript from code to the UI view and respond to user interactions without writing any other codes. 

Custom Components

Developers can create their own custom components that can contain both functionalities and logic for reusable pieces for custom development using Angular. 

Dependency Injection

You can write Modular services during coding and inject them as and when needed. This allows you to test better and reuse the components as and when needed. 

Major Testing Features

Angular provides many robust testing tools to make sure that you can test the entire application from end to end. 

Compatible with All Browsers

Web apps developed with Angular are compatible on all browsers and almost all operating systems.

Key Features of AngularJS

MVC Framework

AngularJs allows you to utilise MVC, which is the Model View Controller model for development. This saves time as you can combine the client side after developing it separately.

HTML for UI Interface

It may be hard to use Javascript for user interfaces so AngularJS provides an HTML interface so you can only provide what you want and AngularJS will create the requisite dependencies. 


AngularJS uses Plain Old JavaScript Objects, that is you don’t need to add additional elements to AngularJS and you can just use JavaScript with additional data sources.

The lack of requirement of any additional outside element makes AngularJS self-sufficient and an attractive option for custom development. 

Massive Support Community

Google actively maintains AngularJS and provides support. AngularJS also has a robust community of developers constantly helping out each other and enhancing knowledge as a whole. 

Two Way Binding

Data binding automatically synchronise data between view & the model. This way whenever the HTML or view component is updated, the related bound model has also updated automatically.

Major Differences Between Angular & AngularJS




Supportive Language Largely uses TypeScript Only JavaScript Supported
Responsive Yes. Fully optimised for mobiles. Not a robust support for Mobiles. 
Architecture Components Based MVC & MVVC
Learning Difficulty It a challenge to learn Angular AngularJS is relatively easy as compared to Angular
Dependency Injection Uses Hierarchical Injection Uses Directives instead of Dependency Injection
Routing Command Can route between multiple views using @Route Config{(…)} Can define routing with @routeProvider.when() 
Command Line Interface Inbuilt AngularCLI tool Doesn’t have CLI tool
Examples Web versions of Gmail, Upwork Netflix & Istock website. 



Both AngularJS vs Angular have certain advantages and disadvantages. However as Angular is the updated version of AngularJs you can opt for Angular for a complete list of features and a relatively more updated platform. You can discuss the specific requirements and best fit from both with our expert developers with one simple phone call and a guarantee of an NDA. Hope this article helped in improving your understanding of both.
