TypeScript, a statically typed superset of JavaScript, is the language of choice for Angular development. TypeScript enhances the development experience with features like type-checking, advanced tooling, and better code refactoring capabilities. This leads to fewer runtime errors and more robust code.

👉 Two-Way Data Binding:

Although many modern frameworks have moved away from two-way data binding, Angular still leverages this powerful feature. Two-way data binding synchronizes the data between the model and the view in real time. This simplifies the development of dynamic applications where the user interface must react to data changes instantly.

👉 Dependency Injection:

Angular's built-in dependency injection system improves code modularity and testing. Dependency injection allows for the efficient management of service dependencies, enabling developers to write more testable and maintainable code. Services can be injected into components, directives, or other services, promoting a clean separation of concerns.

👉 Reactive Programming with RxJS:

Angular extensively uses RxJS (Reactive Extensions for JavaScript) for handling asynchronous operations. RxJS provides powerful operators for managing events, asynchronous data streams, and complex data transformations. This makes it easier to handle user interactions, server responses, and other asynchronous tasks.

👉 Angular CLI:

The Angular Command Line Interface (CLI) is a powerful tool that streamlines the development process. The CLI allows developers to generate components, services, modules, and more with simple commands. It also automates tasks like testing, building, and deploying applications, significantly improving productivity.

👉 Testing:

Designed with testing in mind, AngularJS provides support for both unit and end-to-end testing. Improves code quality and reliability by making it easier to write and run tests.

👉 Document Object Model (DOM) Interaction:

Angular efficiently interacts with the DOM, enabling dynamic updates and manipulation of the view based on data changes. This ensures the user interface responds effectively to user interactions.

👉 Routing:

Built-in support for routing helps in managing the navigation between different views within the application. Thus, it facilitates the creation of single-page applications (SPAs) by enabling dynamic view changes without reloading the page.

👉 Templates:

Templates in Angular define the user interface of the application. They use a combination of HTML and Angular directives to dynamically render the view. Templates bind data and directives to the DOM, creating a dynamic and interactive user experience.

👉 Forms:

Angular provides comprehensive support for building forms with two approaches: template-driven and reactive forms. This flexibility allows developers to choose the most suitable method for their needs.

👉 Services:

Services in Angular are singleton objects that encapsulate reusable business logic and data. They centralize functionality like data fetching, validation, and logging, promoting code modularity and maintainability. Dependency injection allows services to be easily shared across components, ensuring a clean separation of concerns and enhancing testability.

👉 Controller:

In AngularJS, controllers are used to define the application's behavior by exposing the model to the view via the scope. They handle the business logic and interact with services and models. In Angular, components largely replace controllers.

👉 Ahead-of-Time (AOT) Compilation:

 Angular offers AOT compilation, which compiles the application during the build process. This results in faster rendering, improved performance, and earlier detection of template errors.

👉 Animations:

Angular includes a module for creating rich animations. It allows developers to add motion and transitions to the application, enhancing the user experience.

👉 Internationalization (i18n):

Angular offers built-in support for internationalization, making it easier to develop applications that support multiple languages and locales.

👉 Community and Ecosystem:

Angular has a large and active community. The extensive documentation and a rich ecosystem of third-party libraries and tools, aid in rapid development and problem-solving.
