Angular
Angular is a platform and framework for building single-page client applications in HTML and TypeScript.
The architecture of an Angular application relies on certain fundamental concepts. The basic building blocks are NgModules, which provide a compilation context for components.
Components define views. Components use services, which provide specific functionality not directly related to views. Service providers can be injected into components as dependencies, making your code modular, reusable, and efficient.
Each component defines a class that contains application data and logic, and is associated with an HTML template that defines a view to be displayed in a target environment.
A template combines HTML with Angular markup that can modify HTML elements before they are displayed. Template directives provide program logic, and binding markup connects your application data and the DOM. There are two types of data binding: Event binding lets your app respond to user input in the target environment by updating your application data; Property binding lets you interpolate values that are computed from your application data into the HTML.
