What is Angular..?


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 does not have a concept f “scope” or controllers, instead it uses a hierarchy of components as its primary architectural characteristic.
  • Angular has a different expression syntax, focusing on “[ ]” for property binding, and “( )” for event binding.
  • Modularity – much core functionality has moved to modular
  • Angular recommends the use of Microsoft’s  Typescript language, which introduces the following features:
  • Dynamic loading
  • Asynchronous template compilations.
  • Iterative callbacks provided by RxJS. RxJS limits state visibility and debugging, but these can be solved with reactive add-ons like ngReact or ngrx.
  • Support for Angular Universal, Which runs Angular applications on services.

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.



  • Component defines views, which are sets of screen elements that angular can choose among and modify according to your program logic and data.
  • Component use services, which provide specific functionality not directly related to views. Service provides can be injected into components as dependencies, making your code modular, reusable, and efficient.

Modules:- Every angular app has a root module, that named AppModule, which provides the bootstrap mechanism that launches the application. An app typically contains many functional modules. Like javaScript modules, NgModules, can import functionality from other NgModules, and allow their own functionality to be exported and used by other NgModules. For example, use the router services in your app, you import the Router Ngmodule.

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.

  1. Enter a URL in the address bar and the browser navigates to a corresponding page.
  2. Click links on the page and the browser navigates to a new page.
  3. Click the browser’s back and forward buttons and the browser navigates backward and forward through the history of the page you’ve seen.


Future of angular:- Angular is now one of the most loved JavaScript frameworks and a standard for large-scale applications. Angular is helpful for single page application projects. Angular expands the HTL DOMM with extra traits by being totally free and open source. Once you use Angular and TypeScript with a good text editor like Visual Studio Code, your code gains magical abilities to automatically enter your thoughts and figure out which variable you are trying to use, automatically import it, and use it. Long story short, Angular as it is will exist for as long as web applications exist. I fully expect a version of angular in the future to implement all new changes to javaScript and even integrate web Assembly.
