What is Angular?

In Angular, developers use declarative templates with HTML, enhanced by directives and binding syntax, to define the user interface. The framework facilitates two-way data binding, ensuring automatic synchronization between the application’s data (model) and its visual representation (view). This eliminates the need for manual manipulation of the Document Object Model (DOM).

Angular includes a powerful dependency injection system, enabling the management of component dependencies and promoting code modularity. Applications are organized into modules, which help handle complexity by breaking down functionality into manageable units. Services, another key feature, allow the encapsulation and sharing of logic across components.

The framework provides built-in directives that extend HTML functionality, such as creating reusable components and manipulating the DOM. Angular applications benefit from cross-browser compatibility, as the framework addresses common browser-related issues.

Angular CLI, a command-line interface, streamlines development tasks, making it easier to create, build, test, and deploy Angular applications.

Features of Angular

Two-Way Data Binding:
Angular provides two-way data binding, allowing automatic synchronization between the model and the view. Changes in the model are reflected in the view, and vice versa, without explicit manipulation of the DOM.

Modular Architecture:
Angular applications are organized into modules, helping in the organization and separation of concerns. Modules encapsulate different features and functionalities.

Component-Based Architecture:
Angular applications are built using components, which are self-contained and reusable pieces of code. Each component encapsulates its own logic, template, and styles.

Services:
Angular services are reusable singleton objects used to encapsulate and share business logic, data retrieval, and other common functionalities across components.

Directives:
Angular provides a set of built-in directives that extend HTML functionality. Directives can be used for creating custom components, manipulating the DOM, and applying conditional rendering.

Cross-Browser Compatibility:
Angular takes care of many cross-browser compatibility issues, ensuring a consistent experience across different web browsers.

Forms and Validation:
Angular provides a powerful forms module with support for template-driven and reactive forms. It includes features for form validation, making it easier to manage user input.

Dynamic Loading:
Angular supports lazy loading, allowing developers to load modules and components on demand. This can improve application performance by reducing initial loading times.

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.

Features of AngularJS

Two-Way Data Binding:
AngularJS introduced automatic two-way data binding, streamlining the synchronization of data between the model (application logic) and the view (user interface).

MVC Architecture:
Following the Model-View-Controller (MVC) pattern, AngularJS helps structure code by separating it into Model (data and logic), View (user interface), and Controller (handling user input).

Dependency Injection:
The framework incorporates a built-in dependency injection system, aiding in the management and injection of dependencies into components for improved modularity.

Directives:
AngularJS relies on directives to extend HTML functionality, enabling the creation of reusable components and the augmentation of HTML with Angular-specific behavior.

Controller:
Controllers in AngularJS manage user input, facilitate updates to the model, and interact with services, contributing to the separation of concerns within the application.

Services:
AngularJS uses services as singleton objects that can be injected into controllers, promoting the sharing of functionality and data across different parts of the application.

Filters:
Filters in AngularJS allow developers to format and transform displayed data, ensuring a more customized appearance before rendering.

Templates:
AngularJS utilizes HTML templates with embedded Angular-specific expressions, evaluated and replaced with actual data during the rendering process.

Routing:
The framework includes a routing module to create single-page applications with multiple views, facilitating seamless navigation between them.

Testing Support:
AngularJS prioritizes testability, providing support for unit testing and end-to-end testing using tools like Jasmine and Protractor.

Scope:
In AngularJS, the concept of scope establishes the context for evaluating expressions, connecting the model and the view.

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:

Parameter	Angular	AngularJS
Architecture	Angular uses a component-based architecture	AngularJS is based on the Model-View-Controller (MVC) architectural pattern
Language	Angular is based on TypeScript, a statically-typed superset of JavaScript.	AngularJS primarily uses JavaScript for development
Performance	Angular 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 Development	Angular has a separate framework called Ionic for mobile app development	AngularJS, on the other hand, does not have built-in mobile app development support.
Tooling and Ecosystem	Angular 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.
Compatibility	Angular provides some migration tools and guidelines to help facilitate the transition.	AngularJS applications are not directly compatible with Angular.
Dependency Injection	Angular makes use of hierarchical dependency injection to enhance the application’s performance.	AngularJS does not use dependency injection. Instead, it makes use of directives.
Routing	Angular supports routing between multiple views.	AngularJS also allows you to define all the routing information.
