Angular is a popular open-source front-end web framework developed by Google. It is used for building single-page client applications in HTML and TypeScript (a superset of JavaScript), utilizing a component-based architecture. Angular provides a structured framework that enhances the development process by offering features such as data binding, dependency injection, routing, and reusable components.
Key aspects of Angular include:
Component-Based Architecture: Applications are built as a hierarchy of components, each encapsulating its own logic, HTML template, and styling.
Typescript: Angular applications are written in TypeScript, which adds strong typing and other features such as interfaces, enums, and decorators to JavaScript.
Directives: Angular extends HTML with Directives, enabling developers to create custom HTML tags that serve as building blocks for the application.
Data Binding: Angular provides various types of data binding mechanisms, allowing automatic synchronization of data between the component and the view.
Dependency Injection: Angular has a built-in dependency injection mechanism that helps in creating, managing, and injecting dependencies into components or services.
Routing: Angular includes a powerful routing module that enables navigation between views or pages in a single-page application (SPA).
HTTP Client: Angular provides an HTTP client library for making AJAX requests to a server, handling responses, and error handling.
Forms: Angular supports both template-driven forms and reactive forms for handling user input validation and form submission.
Testing: Angular applications are highly testable with support for unit testing and end-to-end testing using tools like Jasmine and Protractor.
Angular's evolution has led to multiple versions (Angular 2, Angular 4, Angular 5, etc.), with Angular being the latest major release. It has gained widespread adoption due to its robust features, strong community support, and its ability to handle complex applications efficiently.
