Angular is a free, open-source framework for building web applications using JavaScript. It is written in TypeScript, a high-performance programming language that eliminates errors while writing codes. It provides two-way data binding, making it easy to create dynamic web applications.
Angular uses a component-based architecture. Each component contains a class that encapsulates application data. Components also contain services, which provide specific functionality not directly related to the view.
Components have a strict hierarchy. They define an HTML template and use services to respond to user input. Each component class also contains metadata, which associates the class with the template that defines the view. This metadata allows developers to use iterators and lambda operators to create dynamic applications.
The Angular CLI tool makes it easy to test and integrate features. It comes with testing tools out of the box. However, some code updates may involve third-party dependencies.
Angular uses HTML syntax to create templates for components. It evaluates the directives before displaying the view.
Components can be written in TypeScript or Dart. Both languages are supported by many popular code editing tools (more infomation).
The Angular CLI tool also provides a workspace to host multiple Angular projects. This makes it easier to migrate between versions. There are also Angular resources, which include tooling, UI environments, and data libraries.
In addition to component classes, Angular also defines decorators. Decorators are markup tags that tell Angular how to use a class. Using decorators can reduce the size of component classes.
