Angular is a framework for building dynamic web applications. Its architecture is based on a component-based design. A component defines a template that renders a view, and the component also defines a class that contains application data. The components also interact with external services.

The structure of the components is hierarchical. Each component has a root component that connects the component hierarchy with the DOM. The component also has a number of decorators. These decorators tell Angular how to use the component. The component is then re-instantiated if the value of a specified directive is true.

The directives allow developers to define special behaviors for the DOM. They also allow engineers to create dynamic content using HTML. It’s not necessary to write a lot of JavaScript code to achieve this.

Injectors are a major feature of Angular. They make components easier to manage and test. They also decouple components from dependencies. This enables developers to reuse components in different projects.

In addition, Angular provides two-way data binding. This allows the application to respond to user input. By removing common boilerplate code, developers can build UIs more easily and intuitively.

Angular also supports data libraries and analytics tools. The data library allows the application to respond to user input and display appropriate values for the user’s locale. This increases the overall efficiency of the application (more information).

The Angular CLI has also been improved. The latest version has a new compilation method that improves the overall performance of the framework. The CLI also includes a NG update command, which checks for updates to packages and other dependencies.
