Angular 2+ is a web development framework for building dynamic, single-page web applications (SPAs) and progressive web apps (PWAs). It is the successor to AngularJS (Angular 1.x) and was officially released by Google in 2016. Angular 2 introduced a complete overhaul of the original AngularJS framework, with significant changes and improvements in terms of architecture, performance, and development experience.
Since its initial release, Angular has seen several version updates, with Angular 10, Angular 11, Angular 12, and so on, each introducing new features, performance improvements, and bug fixes. Angular is widely adopted for building complex and large-scale web applications due to its robust architecture, maintainability, and strong development ecosystem. Apart from it by obtaining Angular Course Content Contant, you can advance your career in Angular. With this course, you can demonstrate your expertise in applications using React concepts such as Angular Modules, Components, Databinding, Angular Forms, Angular Directives and Pipes, Services and Dependency Injection (DI), many more fundamental concepts, and many more.
Key features and concepts of Angular 2+ include:
Component-Based Architecture: Angular 2+ is built around a component-based architecture, where the UI is broken down into reusable components. Components encapsulate the application's logic, UI, and behavior, making the code more modular and maintainable.
Dependency Injection: Angular 2+ provides a built-in dependency injection system that makes it easy to manage and inject dependencies into components. This promotes code reusability and testability.
Templates and Data Binding: Angular uses declarative templates with two-way data binding, allowing developers to bind UI elements to data models and automatically update the UI when data changes. This reduces the need for manual DOM manipulation.
Routing: Angular's router module provides powerful client-side routing capabilities, enabling developers to create navigation paths and load components dynamically based on URL changes.
Forms: Angular offers extensive support for both template-driven forms and reactive forms (model-driven forms). These features simplify form creation, validation, and handling user input.
HTTP Client: Angular includes an HTTP client module for making HTTP requests to servers. It supports features like request and response handling, interceptors, and error handling.
Testing: Angular provides tools and utilities for writing unit tests, end-to-end tests, and integration tests. It encourages test-driven development (TDD) and ensures code reliability.
Internationalization (i18n) and Accessibility: Angular 2+ offers built-in support for internationalization and localization. It also emphasizes creating accessible applications for users with disabilities.
CLI (Command Line Interface): The Angular CLI simplifies project setup, code generation, and development tasks. It streamlines the development process by providing commands for common operations.
Community and Ecosystem: Angular has a large and active community, which contributes to a rich ecosystem of third-party libraries, extensions, and tools. This makes it easier to extend Angular applications with additional functionality.
