What Is Angular?

Angular is an open-source JavaScript framework developed in TypeScript, primarily aimed at building single-page applications. It offers a robust structure that enables developers to create scalable and maintainable applications efficiently.

Why Use a Framework?

Frameworks enhance web development by providing a consistent structure, saving developers time and effort. They come equipped with additional features that streamline the coding process, reducing the need to rebuild components from scratch.

Why Choose Angular?

While JavaScript is the most popular client-side scripting language, Angular addresses the limitations of traditional JavaScript in developing modular and testable single-page applications. It provides solutions to common challenges faced by developers, making it an ideal choice for modern web development.

Versions of Angular

Angular has evolved significantly since its inception in 2009. Initially released as AngularJS, the framework has gone through multiple iterations, with the latest version, Angular 11, introduced on November 11, 2020. Each version enhances the framework's capabilities, addressing bugs and adapting to the complexities of modern applications.

Key Features of Angular

• Document Object Model (DOM): Angular uses a regular DOM, ensuring efficient updates across the application.
• TypeScript: Enhances code readability and maintainability, although it is not mandatory for Angular development.
• Data Binding: Facilitates two-way data binding, connecting the UI and model seamlessly.
• Testing: Built with testability in mind, utilizing frameworks like Jasmine and Karma for comprehensive testing.

Angular Architecture

Angular operates as a full-fledged Model-View-Controller (MVC) framework. Its architecture is composed of several building blocks, including:

1. Modules: The root module, AppModule, serves as the application's bootstrap.
2. Components: Define application logic and UI structure.
3. Templates: Combine Angular markup with HTML for dynamic content.
4. Metadata: Configures class behavior.
5. Services: Share data and logic across components.
6. Dependency Injection: Promotes efficient component classes by delegating tasks to services.

Advantages of Angular

Angular offers numerous benefits:

• Custom Components: Users can create reusable components with embedded functionality.
• Data Binding: Simplifies data movement between JavaScript and the UI.
• Dependency Injection: Enhances modularity and testability of services.
• Comprehensive Framework: Provides built-in solutions for routing and server communication.
• Cross-Browser Compatibility: Runs seamlessly across different browsers and operating systems.

Limitations of Angular

While powerful, Angular does have some drawbacks:

• Steep Learning Curve: Beginners may find it challenging due to its complexity.
• Limited SEO Options: Accessibility for search engine crawlers is restricted.
• Migration Difficulties: Transitioning from legacy systems can be cumbersome.

Difference Between Angular and AngularJS
