What is Angular

This Article helps you to Understand about Angular

The Angular team has published numerous versions since its inception.

Angular Versions 1 and 2 were very distinct frameworks, yet they had several things in common.
To avoid misunderstandings, the Angular team started calling the current version of Angular just "Angular" and the older version of as "AngularJS". AngularJS was written in JavaScript, while Angular was not.

Differences between AngularJS and Angular:

• Angular is a complete rewrite version of AngularJS.
• The main building elements for Angular are modules, components, templates, metadata, data binding, directives, services and dependency injection.
• Angular does not have a "scope" concept or controllers, instead, it uses a component hierarchy as its main architecture.
• Angular follows a modularity concept. This gives Angular an optimized lighter core.
• The controller idea, which was a part of AngularJS, has been dropped from Angular 2 and later, which are component-based UI frameworks. It is now possible for developers to divide programmes into segments with the features they desire..
• Angular, improved the reusability and flexibility over AngularJS.. 
• Angular expression syntax is focused on "[ ]" for property binding, and "( )" for event binding.
• It was difficult to create an AngularJS single page application that is SEO-friendly.But this problem was resolved when Angular 2 enabled application rendering on the server.

Angular also includes the benefits taken from ES6:

• For/Of loops
• Improved dependency injection
• Iterators
• Reflection
• Dynamic loading
• Asynchronous template compilation
• Simpler Routing

Angular Features

• Cross-Platform
  • Progressive web apps: It offers an app-like experience by utilising the features of contemporary web platforms. It offers zero-step installation, offline mode, and great performance. Thus, using Angular is essentially simple.
  • Native: Ionic Framework, NativeScript, and React Native can be used to create native mobile apps with strategies.
  • Desktop: Using the same Angular techniques you've learned for the web, you can create desktop apps that run on Mac, Windows, and Linux..
• Speed and Performance
  • Code generation: Angular turns your templates into code that’s highly optimized for JavaScript virtual machines, giving you all the benefits of hand-written code with the productivity of a framework.
  • Universal: Any technology, including PHP,.NET, Node.js, and other servers, can be used with Angular to serve the application.
  • Code splitting: The new Component Router for Angular apps offers automatic code-splitting so users only load the code necessary to render the requested view, resulting in faster app loads.
• Productivity
  • Templates: Quickly create UI views with simple and powerful template syntax.
  • Angular CLI: Using the Angular CLI, you can begin creating components, adding components, testing them, and then instantaneously deploying them with ease and speed.
  • IDEs: Get intelligent code completion, instant errors, and other feedback in popular editors and IDEs like Microsoft’s VS Code.
  • Testing: The Angular CLI downloads and installs all the necessary files for testing your application using the Jasmine test framework. The Karma test runner will start and the app will be created in watch mode when you run the ng test command. When it's finished, the output will appear in the terminal plus and the Chrome browser will open, displaying the output in the Jasmine HTML Reporter..
