• Angular is a popular open-source web application framework developed and maintained by Google. It is a comprehensive framework for building dynamic, single-page web applications (SPAs) and supports the development of large-scale, feature-rich applications. Angular follows the component-based architecture and embraces declarative programming. Here are key features and concepts associated with Angular:
  1. Component-Based Architecture:
     • Angular follows a component-based architecture, where the UI is divided into modular components. Each component encapsulates its own logic, template, and styles, promoting reusability and maintainability.
  2. Typescript:
     • Angular is built using TypeScript, a superset of JavaScript that adds static typing to the language. TypeScript enhances code quality, provides better tooling support, and helps catch potential errors during development.
  3. Directives:
     • Angular provides a set of built-in directives that enable developers to extend HTML with additional functionality. Directives are used for tasks such as data binding, conditional rendering, and manipulating the DOM.
  4. Two-Way Data Binding:
     • Angular supports two-way data binding, allowing automatic synchronization of data between the model and the view. Changes in the UI update the underlying data, and vice versa.
  5. Dependency Injection:
     • Angular has a powerful dependency injection system that simplifies the management of dependencies in components and services. This promotes modularity, testability, and maintainability.
  6. Services:
     • Services in Angular are used for encapsulating reusable business logic, data fetching, and other common functionalities. Services can be injected into components, providing a way to share functionality across the application.
  7. Modules:
     • Angular applications are organized into modules, which are containers for components, services, and other application features. Modules help in structuring the application and managing dependencies.
  8. Routing:
     • Angular includes a robust routing system that allows developers to define navigation paths and views for SPAs. The Angular Router provides features such as lazy loading, route guards, and nested routes.
  9. Forms and Reactive Forms:
     • Angular offers both template-driven forms and reactive forms. Reactive forms are built using TypeScript and provide a more programmatic approach to form handling, including powerful validation and asynchronous operations.
  10. HTTP Client:
      • Angular includes an HTTP client module for making HTTP requests to servers. It supports features such as request and response transformations, interceptors, and observables for handling asynchronous data.
  11. Animations:
      • Angular has a built-in animation module that allows developers to create rich animations in their applications. Animations can be applied to components, directives, and routes.
  12. Testing Support:
      • Angular provides tools and utilities for writing unit tests and end-to-end tests. The Angular testing framework is designed to facilitate testing components, services, and other parts of the application.
  13. Angular CLI (Command-Line Interface):
      • Angular CLI is a command-line tool that helps developers scaffold, build, and maintain Angular applications. It streamlines the development process and provides commands for generating components, services, modules, and more.
  14. Internationalization (i18n):
      • Angular supports internationalization and localization, making it possible to create applications that support multiple languages and regions.
  15. Community and Documentation:
      • Angular has a large and active community of developers. The official documentation is comprehensive and serves as a valuable resource for learning and reference.

  Angular is widely used in building modern web applications and is known for its scalability, performance, and rich feature set. It is suitable for a range of applications, from small projects to enterprise-level applications.

• The most popular client-side programming language is JavaScript. It is included in HTML files to enable a variety of unique interactions with online pages. It is a fantastically simple language with widespread support that is well-suited to enhancing contemporary applications.
• But is JavaScript the greatest language for developing modular, testable, and productive single-page applications? Maybe not.
• There are several frameworks and libraries available nowadays that are meant to offer superior solutions. It addresses many with an appreciation for front-end web development. If not all, of the issues that come up when developers utilize JavaScript alone.

You need a smart framework to create smart websites, and the most popular one is Angular.
A forward-thinking bunch of techies created Angular intending to simplify web development. They had a common ambition of having enjoyable and pleasurable web development experiences while creating lovely products.
With the support of this vision, Google unveiled Angular in 2009 under the moniker ‘AngularJS’. It was an unreliable framework with a sizable collection of libraries. As a result, Google developed Angular, an open-source framework that is built on TypeScript and is AngularJS’s offspring.
The most widely used front-end development tool to date, Angular is a crucial component of the JavaScript ecosystem. The most recent version is Angular 8, which came out after Angular 2.0. Each Angular variant. Every Angular version has several features and has been updated with more intelligent elements.
The following are some of the basic and technical characteristics of this widely used front-end framework.

Cross-Platform

You may create progressive web apps with Angular (PWA). PWA utilizes contemporary web features to provide users with an experience similar to an app. You may deploy an app as native or progressive depending on your needs. Your apps may be published to the app store and made available on the mobile web as PWAs using the hybrid mobile SDK known as Ionic. Moreover, Angular allows you to create desktop applications.

High Performance and Speed

By converting templates into code, Angular redefines the current JavaScript virtual machine. As a result, the code you wrote by yourself can benefit from a useful framework. The best feature of Angular is that you can render the code into HTML and CSS and see the application’s front end on any other platform, like NodeJS,.Net, PHP, etc. Angular apps load more quickly than any other front-end framework used today. With any new component router, it loads at cheetah-like speeds. Moreover, the code is automatically divided based on the user’s loading and rendering needs.

Applications Using Angular for Everyone

In addition to enabling the development of mind-blowing apps, Angular is a fantastic front-end framework that also makes it possible to produce top-notch animations to improve user experience. Because of Angular’s simple API, programmers can create intricate animations and choreographies with little code. 

In addition, you can always correct your faulty code thanks to sophisticated unit testing tools like Jasmine and Karma. To guarantee error-free programming, Angular provides more than 11 built-in testing modules. 

Creating accessible apps is one of Angular’s ground-breaking features. The accessible programs are used by everyone, including those with particular talents.

MVC Architecture

MVC, or model-view-controller, is an acronym. The Model handles the application data, and the View manages the data presentation. While serving as a link between the view and model layers, the controller. With MVC design, you can typically divide the program into its parts and create code to connect them. Nevertheless, with Angular, developers only need to divide the application into MVC; the framework takes care of the rest automatically. Also, it cuts down on coding time significantly.

Two-Way Data Binding That Is Effective

The two-way data binding system of Angular is its most useful component. The View layer perfectly replicates the Model layer, and they remain in sync. Users may see any changes you make to the model automatically in the view model. As a result, it cuts down on crucial development time.

Framework with less code

Compared to other front-end technologies, Angular is a low-code framework. The MVC layers don’t need to be linked separately in the code. Moreover, viewing manually does not require any special code. The directives are also separated from the app code. The development time is automatically reduced by all of these.

Angular CLI (Command Line Interface)

The Angular CLI includes eye-catching built-in capabilities like SCSS support or routing while adhering to the frontend development industry’s best practices. Moreover, the ubiquitous Angular CLI tools like ng-new and ng-add let developers find pre-made features with ease. Angular’s basic CLI is as follows:

• ng New: Its use is essential to the creation of every Angular project. Moreover, this function allows you to create a new workspace.
• You may generate new components, services, routes, and pipes with ng Generate. Also, ng Generate allows you to build straightforward test shells.
• You may test your Angular app on a local server with ng Serve.
• Shine your code with clever unit and end-to-end tests, says Test, Lint. Moreover, ng lint aids in running programs that evaluate code for potential mistakes.

Angular Material and CDK

With version updates, Angular, a leading frontend language, has enhanced its Component Development Kit (CDK). The most notable characteristics of the most recent Angular CDK are refreshing and virtual scrolling. To produce a long list of high-performing data, it aids in dynamic loading as well as unloading of the DOM. The application can import either the DragDropModule or the ScrollingModule.

List sorting, free dragging, previews, and placeholders are some of this DragDropModule’s standout features. Moreover, it facilitates moving objects within and across lists (moveItemInArray) (transferArrayItem)

Angular Virtual Scrolling 

The code may respond to different scroll events thanks to virtual scrolling. In addition to loading and unloading visible DOM components, Virtual Scrolling provides a useful method for simulating objects.

TypeScript

Angular provides developers with a smooth experience thanks to TypeScript. And the most popular choice for frontend development in 2019 is TypeScript. Because it is so effective at finding flaws, it shortens the time needed for development. For streamlined compilation, TypeScript also automatically populates the root file settings. Richer enums, interfaces, generics, hybrid types, union/intersection types, access modifiers, etc. are available in TypeScript as opposed to JavaScript.

Dependency Injection

The built-in dependency injection of Angular facilitates developers’ work while creating applications. Only your dependencies are requested. Just say, “I need y.” And it produces the identical thing and gives it to you.

Directives

The trickiest Angular features are directives. With the use of directives, you may make personalized HTML tags that function as personalized widgets. These can be used by developers to embellish behavior-driven features. With the aid of directives, you may also modify DOM characteristics according to requirements.

Organizing everything in one place

In the market, Angular already occupies a promising position. This top framework is wildly popular because of its exceptional accessibility and low code features. Several well-known websites use Angular in their web development, and the results are well-known to everybody. Examples include Samsung Forward, Deutsche Bank Developer Portal, Microsoft Office Home, Delta, Forbes, BMW Locate a Dealer, BMW Driveaway Pricing Calculator, Google Marketing Platform, and many more. Go Angular, then!
