Table of Content

Nowadays, many JavaScript frameworks are available in the market that is explicitly used for web and mobile app development. If we talk about front-end development, Angular and AngularJS are the most popular frameworks that are hitting the market.

But what’s the major difference between them? Do they really differ from each other? Such questions might be hitting your mind. To answer such questions, we have come up with an article that demonstrates the difference between Angular vs. AngularJS.

Before we start to understand the concept of Angular Vs AngularJS, let us have a look at the basics of AngularJS and the Angular framework.

What are the Types of Angular Versions?

We will differentiate between all the versions of Angular in detail below. But before that, let’s understand what every version brings to the table and the major difference between them. 

Angular JS

  • It’s an official name, but it is often known as Angular 1. 
  • An open-source and front-end web application framework that typically uses JavaScript technology. 
  • You can effectively utilize HTML programming language as a template for responsive design. 
  • In AngularJS, you can quickly combine the data and expressions for designing and developing web applications. 
  • AngularJS helps simplify the testing and application development process by strictly following a framework for client-side model–view–controller (MVC) and Model–View–ViewModel (MVVM) architectures. 
  • You can even create components that are vital in building rich Internet applications.
  • It uses the controller approach where the view communicates using a $scope.

Angular 2

  • The next version of AngularJS is Angular 2. 
  • Unlike AngularJS, Angular 2 is not a regular update. 
  • It’s a complete rewrite of its counterpart. 
  • Angular 2 uses the component-based approach in developing HTML and JavaScript Web applications for your business needs.

Angular 4

  • Angular 4 is a typescript-based open-source and front-end framework for web app development. 
  • Being the successor of Angular 2, Angular 4 is not a complete rewrite, and both versions use the same patterns and concepts. 
  • Angular 4 comes up with advanced features like smaller and faster apps, an animation package, AS keywords, etc.

Angular 5

  • After Angular 4, Angular 5 was launched with more advanced and enhanced features for efficiently designing and building web applications.
  • The excellent part of Angular 5 is that it makes it easy for Angular developers working in leading AngularJS development companies to remove unnecessary codes from their applications.
  • Other improved features are a code-sharing feature, less time for assembling dynamic web applications, and so on. 
  • Moreover, it has DOM support, and its compiler helps with incremental compilation.

Angular 6

  • The improvements in this Angular version 6 are even better than previous versions. 
  • Angular 6 is the framework introduced to make the web parts of applications that can quickly deal with most cutting-edge browsers. 
  • Its impressive features of Angular 6 bring convenience in creating Angular web component and using it in various HTML pages later.

Angular 7

  • Angular 7 framework helps you to build web apps using leading technologies like HTML, Javascript, and Typescript. 
  • With the help of Angular 7, you can quickly grab the features like better mobile apps with CLI prompts, drag-and-drop functionality, improved app performance, component dev kit (CDK), and virtual scrolling with this framework. 

Angular 8

  • Angular 8 supports Ivy as the default rendering engine. 
  • Some of the best features of Angular 8 include differential loading of modern JavaScript, support for web workers, and dynamic support for lazy routers.
  • Angular 8 was more famous for the much-anticipated Ivy compiler as an opt-in feature. 

Since Angular version 9+, there are some minor updates introduced compared to previous versions.

Angular 9 

  • Angular 9 came up with new and enhanced Ivy compiler and runtime features, a better debugging process, quick testing, and many more improvements that make it easy for you to deal with the web app development process. 
  • Angular 9 is most popularly known for its Ivy default compiler and improved bundle size.

Angular 10 

  • Angular 10 represents new dynamic features of the “new date range picker” in the Angular Material UI component library.
  • Moreover, you will also find additional features like warnings for CommonJS imports and more exciting features on the Angular 10 version. 

Angular 11

  • Like Angular 10, Angular 11 include stricter types, automatic font inlining, and router performance improvements.
  • Angular 11 is an Angular framework version that allows you to smoothly design and build web applications from scratch.

Angular 12

  • In Angular 12, the View Engine has finally been deprecated.
  • Angular 12 allows you to migrate from legacy i18n message IDs quickly
  • It allows you to start new or running tasks, and you can even furnish alternatives with famous 3rd party solutions in the Angular CLI.
  • It eliminates support for IE11 in Angular v12.

Angular 13

  • Angular 13 support TypeScript 4.4.
  • Angular 13 is 100% Ivy
  • A new type called FormControlStatus has been added in Angular 13. 
  • In Angular13, the router will no longer supplant the browser URL whenever the new navigation cancels the ongoing navigation.

Angular 14

Till date, Angular 14 is the latest version of the Angular framework. Angular 14 came up with the latest features and updates that you must be aware of while creating or upgrading the Angular versions.

  • In Angular 14, TypeScript versions older than 4.6.0 are no longer supported.
  • Make sure you are using Node 14.15.0 or later.
  • It supports Reactive form types such as FormControl and FormGroup now have generic type parameters and infer stricter types.

What is the AngularJS Framework?

AngularJS is an open-source web application framework for developing dynamic web applications. AngularJS helps you utilize HTML as a template language and lets you extend HTML’s syntax to express your application’s components clearly and concisely.

AngularJS is entirely based on HTML and JavaScript. The primary role of AngularJS is to change static HTML to dynamic HTML. The entire coding structure of AngularJS is divided into JavaScript files and can be embedded into a web page using the <script> tag.

Top Features of AngularJS Framework

After having a look at the basics of what is Angular, it’s high time to explore the best features of the AngularJS framework.

Angularjs Framework Features

  1. MVC (Model-View-Controller)

    AngularJS framework typically uses the MVC approach for developing web applications. This design pattern is meant explicitly for splitting the business logic layer, the data layer, and the presentation layer into separate sections.

    • Model is considered to be the lowest level of the pattern specifically for maintaining data.
    • The View is responsible for displaying all or a portion of the data to the user.
    • The Controller is nothing but a software code that efficiently controls the interactions between the Model and View.
  2. Data Model Binding

    AngularJS makes it easy for the developers to add a few code snippets directly into the structure, irrespective of writing additional code to bind data. Furthermore, once you add some code snippets, it becomes easy for you to attach data directly from HTML control to application data.

  3. Writing Less Code

    AngularJS framework has become a boon for Angular developers as it allows them to write less amount of code for DOM manipulation. Moreover, the developers are free from writing long code structures for building web applications.

  4. Unit Testing

    The Google development team has not only introduced the AngularJS framework but has defined a testing framework named “Karma”. The primary role of Karma is to help developers to design a unit testing approach for AngularJS applications.

  5. Directives

    Directives in the AngularJS framework are real-time markers on the DOM element that instructs AngularJS to attach a specified behavior inside the application. Moreover, it is responsible for handling the DOM element or even transforming it with its children.

    In simple words, we can say that AngularJS extends HTML with additional attributes, “directives”. AngularJS has a set of built-in directives which offers functionality to the applications. It also defines its directives. Angular provides a way to create custom directives too.

  6. Not-Browser Specific

    Angular applications do not involve any browser constraint. Therefore, it can efficiently run on all major browsers such as Chrome, Firefox, Safari, IE8, and Android, except internet explorer 8.0.

  7. Dependency Injection

    With the help of dependency injection, it becomes easy for AngularJS developers to design and build applications faster. Moreover, it allows an application easier to test. It allows you to ask for your dependencies rather than having to look for them or make them by yourself.

AngularJS Architecture

AngularJS Architecture

  • Controller: The Controller is an integral part of the AngularJS application. Its primary duty is to represent the essential layer that typically covers the business logic. The event-triggering function occurs, whenever the user makes clicks on it. All the essential functions are stored inside the controller.
  • Views: Views are an essential aspect of the AngularJS application that is primarily used to represent the presentation layer that is provided to the end-users.
  • Models: Models are used to represent your data. The data in your model can be as simple as just having primitive declarations. For example, if you are maintaining a student application, your data model could just have a student id and a name.
    Or it can also be complex by having a structured data model. If you are maintaining a car ownership application, you can have structures to define the vehicle itself in terms of its engine capacity, seating capacity, etc.

Pros and Cons of AngularJS Framework

Pros Cons
 Two-Way Data Binding  JavaScript Support Mandatory
 DOM Manipulation  Inexperience With MVC
 Improved Server Performance  The Scope
  Faster Application Prototyping  Other Complex Feature
 Responsive Web App  Possible Time Consumptions
 Highly Testable Product  Difficult Learning

Pros of AngularJS

  1. Two-Way Data Binding

    AngularJS facilitate faster and easier data binding which doesn’t require a developer to interfere at all. Referred to as two-way data binding, it ensures that changes made to view are instantly displayed in the model and vice-versa.

  2. DOM Manipulation

    Unlike other popular JavaScript frameworks, Angular conveniently relieves the developer of actively manipulating DOM (Document Object Model), all thanks to its two-way data binding approach. It means that the developer saves time and effort in code, translating and updating the DOM elements.

  3. Improved Server Performance

    Because it supports caching and many other processes, Angular reduces the burden on server CPUs. It means that the server performs extremely well thanks to reduced traffic and because it only serves static files and responds to API calls.

  4. Faster Application Prototyping

    Rapid prototyping is indeed a buzzword thanks to the existence of frameworks like Angular. In no time and by writing significantly less code, you can develop app prototypes with good functionality, obtain feedback and make changes without getting annoyed.

  5. Responsive Web

    There’s nothing better than arranging an outstanding end-user experience and AngularJS makes it possible by letting responsive, fast-loading and seamlessly-navigating websites and apps.

  6. Highly Testable Products

    One of the underlying aspects of Angular is that it builds highly testable websites and applications. Allowing unit testing and end-to-end testing makes testing and debugging much simpler than you can imagine. Dependency injections, for example, allow various components to be isolated and mocked. Protractor, Jasmine and Karma are other unique testing tools that the framework offers.

Cons of AngularJS

  1. JavaScript Support Mandatory

    It’s pretty obvious that your computer or laptop usually handles the server. And your server must be a JavaScript-supported system as you need to control the overall design. Moreover, the users will not be able to access your system if your server is not Javascript-supported.

  2. Inexperience with the MVC Approach

    The Angular framework becomes somewhat complex if developers use the traditional approach to develop web applications. It becomes possible for the developers to adopt the MVC approach for making the Angular responsive application. Angular becomes time-consuming if they are unaware of the MVC architectural pattern.

  3. The scopes

    Scopes in the AngularJS framework can be rugged for the developers to handle the functionality. The primary reason is it follows a layered and arranged hierarchical flow. Besides, debugging the scopes becomes the prime destruct for the developer while developing the application.

  4. Other Intricate Features

    Utilizing directives in AngularJS is somewhat challenging for the developers. Apart from directives, other essential AngularJS features like dependency injections and factories bring more complexities for traditional developers.

  5. Possible Time Consumption

    With the help of the AngularJS framework, the browser may usually take time to make pages of websites and applications. The primary reason behind it may be due to overloaded browser functionality like DOM manipulation.

  6. Tough Learning

    Instead of approaching a straight learning graph, the developers may find it challenging to adopt the AngularJS framework. In addition, the limited documentation available may further affect the learning process. However, the day-by-day extending community is making it more manageable.

What is Angular?

AngularJS is the first and foremost version of Angular. After the release of AngularJS, Angular 2+ is commonly known by the name “Angular”. It’s normally a framework that is specifically used for building client applications in HTML and either JavaScript or a language like a TypeScript that compiles to JavaScript.

The Angular framework typically consists of multiple libraries, intending to make web applications more responsive and secure.

When we talk about building an Angular application, it means that the developers usually compose HTML templates, write component classes to manage those templates, add application logic in services, and box components and services in modules.

Top Features of Angular Framework

Top Features of Angular Framework

  1. MVC Architecture

    MVC stands for Model-View-Controller. Model typically manages your application data, while data display is handled by View. The primary role of the Controller is to play as an intermediator between View and Model.

    The MVC architecture in the Angular framework easily splits the application and writes the code for connecting the same approach. The Angular developers need to break the entire code and leave the rest to the Angular framework. It saves a significant amount of coding time.

  2. Two-Way Data Binding

    The View layer in the Angular framework represents the Model layer, and it remains in perfect synchronization. Therefore, if the developer makes any consecutive change in the model, the users can see it in the view model automatically. Thus, it minimizes crucial development time.

  3. Few Code Framework

    Compared to other front-end frameworks, Angular is considered a low code framework. In simple words, we can say that the developers need not write different code to link the MVC layers.

    Moreover, they don’t require specific code to view manually also. In addition, the directives are isolated from the app code. These all together automatically minimize the development time.

  4. Angular CLI (Command Line Interface)

    The Angular CLI plays a vital role in AngularJS development services. It includes various built-in features like SCSS support or routing features making the application more responsive.

    However, many Angular CLI available in the market makes the Angular development easy for the developers. Some of the standard Angular CLI are as follows:

    • ng new: To initialize Angular app development or to create a new workplace, this command plays an important role.
    • ng generate: With the help of this command, the developers can quickly create new components, services, routes, and pipes. Not only that, it allows you to create simple test shells for your Angular applications.
    • ng serve: This command allows you to test your Angular app on a local server.
    • Test, Lint: The developers can efficiently perform smart unit and end-to-end tests for your entire coding structure. And ng lint helps to run programs to analyze code for possible errors.
  5. TypeScript

    Angular strictly follows TypeScript language. With its active support of TypeScript, Angular offers a persistent experience to the developers. Moreover, the developers find it easy to identify bugs and reduce developing time.

    The primary role of TypeScript is to populate the root file configuration for easy compilation automatically. TypeScript has richer enums, interfaces, generics, hybrid types, union/intersection types, access modifiers, etc. than JavaScript technology.

  6. Directives

    Being an integral part of Angular applications, Directives allow the developers to create custom HTML tags that usually serve as custom widgets. Developers can use these to decorate behavior-driven elements. Angular developers can efficiently handle the DOM manipulation as per the project needs.

Angular Architecture

The Angular application architecture typically includes the eight essential building blocks.

Angular architecture patterns

  • Modules: Every Angular application has a mandatory root module, defined by the  name “AppModule”. It is nothing but the bootstrap terminology that is responsible for launching the application.
  • Components: At least one component is essential for the Angular project that needs to be built. The root component and root component are two main components that connect the component hierarchy with a page document object model (DOM).
  • Templates: The primary role of Angular template is to simply combine the HTML with Angular markup that can quickly modify HTML elements before they are displayed.
  • Metadata: Metadata is functionality that informs Angular for class processing. It’s essentially used to decorate the class so that it can configure the expected behavior of a class.
  • Data Binding: Data binding plays an important role in communication that acts as an intermediatory between a template and its related component.
  • Directives: We can say that Angular components are nothing more than that a directive with the template. Directives are the building blocks of Angular projects.
  • Services: Service classes are created that play a vital role in data or logic presentation that isn’t associated with a specific view. The @Injectable decorator immediately precedes the service class definition.
  • Dependency Injection: Dependency injection (DI) lets you keep your component classes lean and efficient. DI does not fetch data from a server, validate the user input, or log directly to the console instead they delegate such tasks to the services.

Pros and Cons of Angular Framework

Pros Cons
 Google-Supported framework  Limited SEO Options
 Third-Party Integration Support  Difficult to Learn
 Faster Load Time  Time Consuming
  Customizable Framework  Application Scaling
 Dependency Injection  Not Good For Simple Web App

Pros of Angular

  • Google-supported Framework: Angular is a leading framework that is usually supported by Google, making it easy for the developers to build a dependable, trustworthy program. Moreover, the application works as per Google’s latest updates and announcements.
  • Third-Party Integration Support: The good part of the Angular framework is that the developers can easily include third-party integration supports for the application. In addition, the developers can quickly utilize more Angular development tools to improve the overall form and function of their product.
  • Faster Load Time: Faster load time and enhanced security are additional and essential features that Angular offers. With its “ahead-of-time” compiler functionality, Angular compiles HTML and TypeScript into JavaScript during the entire Angular development lifecycle. All the code is compiled before the browser even loads your web app.
  • Customizable Framework: Angular supports various elements and modules, giving more power to the developer and designer. Apart from building elements and modules, it allows the Angular developers to include such elements directly to projects that were created using another framework.
  • Dependency Injection: It’s the most advantageous for the developers, if and only if, they are aware of its usage. Designing and building multiple dependencies can be time-consuming for the developers, but it can be used well, especially for large-scale projects.

Cons of Angular

  • Limited SEO Options: One of the major disadvantages that come with Angular is that it has limited SEO options and weak accessibility for search engine crawlers. Being that Google is the number one search engine globally, this issue persists for much longer before a solution is presented in another Google update.
  • Difficult to Learn: Another drawback that comes up with the Angular framework is that it can be quite difficult to learn.
  • Time-Consuming: Angular framework is equipped with multiple web modules, coding languages, integrations and customizing capabilities. Initially, the developers require some amount of time to learn the basic structure of Angular. Once they are aware of the framework, it becomes easy to build a new Angular application from scratch.
  • Application Scaling: Unless you’re working on a project of appropriate size and complexity, Angular can easily weigh you down. Save this one for the big-ticket assignments and you’ll fare just fine.
  • Not Good For Simple Web App: To design and build simple web applications, Angular is not a good choice.

Understanding Components of Angular vs. AngularJS

The one thing that usually separates Angular from AngularJS is the Components. We all know that AngularJS is a JavaScript-based framework while Angular 2+ versions is a TypeScript-based framework, and Components is one such terminology that differentiates between AngularJS Vs Angular.

Angular typically uses TypeScript language, which is a superset of ES6. It supports backward compatibility with ES5. On the other hand, Angular JS, a framework entirely based on JavaScript, uses terms of scope and controllers, while Angular uses a hierarchy of components. In addition, Angular is component-based, while AngularJS uses directives.

Use of Directives Between Angular vs. AngularJS

You can use directives in both Angular and AngularJS. But the main question that arises here is how to use them. And that’s what really matters. Angular has standard Directives, while AngularJS has a pack of them. One has to be cautious while using the Directives. 

Let’s go through a simple example. You can use “ng-model” in AngularJS to create two-way data binding in your application. At the same time, you can use “ng-bind” for creating one-way data binding in Angular applications.

In Angular, you will find only the ngModel. You can use the symbols for one-way binding as:” []” and two-way binding as:” [()].”  “[]” is for property binding, while “()” is for event binding.

Difference Between Angular vs. AngularJS

The following table of Angular Vs AngularJS depicts the complete difference between the two front-end development technologies

Features Angular AngularJS
Language It is written in Microsoft TypeScript language. It is written in JavaScript language.
Architecture Angular typically uses components and directives as an architectural design. Model-View-Controller.
Mobile-Support The Angular applications built are entirely mobile-supported applications. The applications developed with AngularJS are not mobile-friendly.
Expression Syntax ( ) and [ ] are the two common attributes that are used for two-way data binding between view and model. {{ }} expressions are typically used for a two-way binding that exists between view and model. ng-bind can also be used to do the same.
Dependency Injection Angular application supports hierarchical dependency injection. There is no usage of dependency injection in the AngularJS application.
Routing Functionality @RouteConfiguration {(…)} is the coding that the Angular team typically utilizes for defining routing information. @routeProvider.when ( ) is the coding that AngularJS development utilizes for configuration and routing information.
Management Angular code has a better structure, and it is easy to create and manage large Angular applications. AngularJS project is difficult to manage with increasing the size of the source code.
Speed Angular applications are faster compared to AngularJS applications. With its two-way data binding feature, AngularJS applications are fast.
Flexibility More flexible and scalable as compared to AngularJS. Less manageable and scalable as compared to Angular.

Angular vs. AngularJS: Which is Better For Your Business Needs?

AngularJS is a leading framework that supports wide scope for structuring exceptional single-page web apps.

On the other hand, Angular versions are highly preferable as a robust front-end tool supplying components that becomes a boon for Angular developers to deal with:

  • Write and re-write
  • Easy-to-use
  • Readable
  • Maintainable code

With its valuable concepts and functionalities, it gets the application to run fast and be stable. In fact, the Angular version provides several benefits to front-end developers, and that makes the popular reason that many companies use Angular for their projects.
