What is Angular?

Angular is a popular open-source framework that developers use for building web applications. It is developed and maintained by Google. Angular is based on TypeScript, a statically-typed superset of JavaScript, and it follows the Model-View-Controller (MVC) architectural pattern.

Angular provides a comprehensive set of tools and features that allow developers to create dynamic, scalable, and maintainable web applications.

Features of Angular

Two-way data binding: Angular provides two-way data binding between model and view components that allows automatic synchronization of data between the model and the view. In simple words, whenever you make some changes in the view or UI elements, the changes will be reflected in the model and vice-versa.

Component-based architecture: Reusable components are used to construct Angular applications. Because each component contains its own logic, data, and view, the program is simpler to manage and update.

Dependency injection: Angular has a built-in dependency injection system that helps manage the dependencies between different parts of an application. It allows for more modular and testable code.

Directives: Angular provides directives, such as ngFor and ngIf, which enable developers to extend HTML with additional functionality. Directives can be used to change the DOM, add or remove elements, and give HTML elements dynamic behavior.

Routing: Thanks to Angular’s built-in router, developers can create single-page applications with various views. It enables view shifting and helps in handling the state of the application.

Reactive programming: Angular embraces reactive programming concepts with the use of RxJS (Reactive Extensions for JavaScript). Developers can manage automated events and processes in a more declarative and controllable manner thanks to reactive programming.

What is Angularjs?

Angular has a large and active community, Hire angular developers who have access to a wealth of tools, tutorials, and third-party libraries. It is widely used in the sector to create complex and scalable online applications.

AngularJS, often referred to as Angular 1, is an older version of the Angular framework. It was also developed by Google and released in 2010. AngularJS introduced a new approach to web application development by extending HTML with additional features and providing a framework for building dynamic and interactive web applications.

AngularJS uses the Model-View-Controller (MVC) architectural pattern, similar to its successor Angular. However, there are some notable differences between the two versions.

Features of AngularJS

Two-way data binding: Two-way data binding, which enables automated data synchronization between the model and the view, was introduced by AngularJS. Any modifications made to either the model or the view immediately affect the other.

Directives: AngularJS introduced directives, such as ngModel, ngRepeat, and ngIf, to extend HTML and add dynamic behavior to elements. Directives can be used to manipulate the DOM, show or hide elements, and bind data to HTML attributes.

Dependency injection: The built-in dependency injection system in AngularJS is similar to that in Angular and aids in managing dependencies between components while enabling modular and testable development.

Templating: AngularJS uses HTML templates with additional markup and directives to define the structure and behavior of views. Templates are compiled and rendered by AngularJS to generate the final HTML.

Routing: A routing module that is already included in AngularJS enables developers to build single-page apps with numerous views. It offers the ability to switch between views and control the state of the program.

It’s important to note that AngularJS and Angular (versions 2 and above) are different frameworks with different syntax, concepts, and architecture. While AngularJS is still in use in some legacy applications, it is generally recommended to use the newer versions of Angular for new projects as they offer enhanced performance, improved features, and better support from the Angular team and the community.

Difference Between Angular and AngularJS

Both AngularJS and Angular are frameworks for building web applications, Angular is a more modern and powerful version of the framework. It offers enhanced performance, improved tooling, a more robust architecture, and better support for mobile app development.

The following comparison will help you understand the differences between Angular and AngularJS based on a number of key parameters:

ArchitectureAngular uses a component-based architectureAngularJS is based on the Model-View-Controller (MVC) architectural pattern
LanguageAngular is based on TypeScript, a statically-typed superset of JavaScript.AngularJS primarily uses JavaScript for development
PerformanceAngular uses a more efficient change detection mechanism, resulting in better performance and reduced memory consumption. AngularJS comes with two-way binding that facilitates the creation of dynamic web pages. Thus, AngularJS applications also offer impressive performance.
Mobile DevelopmentAngular has a separate framework called Ionic for mobile app developmentAngularJS, on the other hand, does not have built-in mobile app development support.
Tooling and EcosystemAngular has a more mature ecosystem with a wide range of tools, libraries, and community support.AngularJS has a supportive community, but it may have fewer active resources and third-party libraries compared to Angular.
CompatibilityAngular provides some migration tools and guidelines to help facilitate the transition.AngularJS applications are not directly compatible with Angular.
Dependency InjectionAngular makes use of hierarchical dependency injection to enhance the application’s performance.AngularJS does not use dependency injection. Instead, it makes use of directives.
RoutingAngular supports routing between multiple views.AngularJS also allows you to define all the routing information.
