AngularJS is a JavaScript-based web framework that was developed to create single-page applications. It was created and maintained by Google and a community of individuals and corporations. The framework has since been discontinued, but its code continues to be open-source and free of charge. The project is a great resource for anyone interested in building and maintaining web applications.

The framework includes a command-line interface for building and testing your app. It also includes prebuilt components for forms, navigation, layouts, buttons, indicators, popups, modal windows, data tables, and more. These components can be easily integrated into your project and are easy to use. Angular also comes with a command-line interface, which makes it extremely easy to test your code.

In Angular 6, the ng update command is used to check if the framework has received any new updates. It also recommends that all dependencies be updated. This includes plugins and loaders. Some updates may be complicated, but others will be automatic. If you have any questions, refer to the Angular Update Guide.

Angular uses a two-way data binding approach that allows it to handle data changes in the DOM. This means that any change made in the DOM reflects the changes made by the program. Angular also provides pipes to transform values for display. For example, if you want your app to show up in the local language of the user, you can make a pipe that displays a country-specific value.
