Each Angular application has a component hierarchy. Each component defines a class that contains the data for an application, as well as an HTML template. This component hierarchy is connected to the DOM by using the @Component() decorator, which identifies the class as a component and provides a component-specific template. Decorators modify the JavaScript classes to enable the application to respond to user input.
Angular has a strong focus on building modern applications with high performance and high quality. The Angular web framework supports modern web policy, type checking, lambda operators, and a declarative template language. Additionally, Angular is optimized for cross-platform development and native mobile development. The framework also supports change detection and unit testing.
Angular is a great framework for building modern, scalable applications. It is much easier to maintain and create complex applications with Angular than with AngularJS. In addition, Angular supports mobile development, unlike AngularJS. Angular has helped construct many popular web apps, including PayPal, Google Mail, and Upwork.
