Angular company referred to as “ Angular v2 and above” is a Typescript-based open-source web application framework led by the angular Team at Google and by a community of individuals and corporations. Angular is an app-design framework and development platform for creating efficient and sophisticated single-page apps.
Differences between Angular and AngularJS :
Angular is a platform and framework for building single-page client applications using HTML and TypeScript. Angular is written in TypeScript. It implements core and optional functionality as a set of TypeScript libraries that you import into your apps.
The architecture of an angular application relies on certain fundamentals concepts. The basic building blocks are NgModules, which provide compilation content for components. An app always has at least a root module that enables bootstrapping and typically has many more feature modules.
Components:- Every Angular application has at least one component, the root component that connects a component that connects a component hierarchy with the page document object model. 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.
Services and dependency injection:- For data or logic that isn’t associated with a specific view, and that you want to share across components, you create a service class. A service class definition is immediately preceded by the @Injectable() decorator. The decorator provides the metadata that allows other providers to be injected as dependencies into your class.
Routing:- The angular Router NgModule provides a service that lets you define a navigation path among the different application states and view hierarchies in your app.
