This Article helps you to Understand about Angular

Angular is a Typescript-based open-source framework for building client-side web applications. Typescript is a superset of JavaScript.
Google maintains Angular, a TypeScript-based JavaScript framework. It integrates seamlessly with other libraries and is completely expandable.

The Angular team has published numerous versions since its inception.

Although they were quite different frameworks, Angular Versions 1 and 2 shared a few characteristics.
The Angular team began referring to the new version of Angular simply as "Angular" and the older version of Angular as "AngularJS" in order to reduce misunderstanding. While Angular was not written in JavaScript, AngularJS was.

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.
  • In Angular 2 and later, which are component-based UI frameworks, the controller concept—which was included in AngularJS—has been eliminated.
    Developers can now partition programmes into parts with the functionalities they want.
  • Compared to AngularJS, these enhanced the flexibility and re - usability.
  • Angular expression syntax is focused on "[ ]" for property binding, and "( )" for event binding.
  • Building an SEO-friendly Single Page Application with AngularJS was quite challenging.However, Angular 2 enabled application rendering in the server, which removed this issue. .

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

1. Cross-Platform
    A. Progressive web apps: It uses modern web platform capabilities to deliver an app-like experience. It gives high performance, offline, and zero-step installation. So, working with Angular is pretty much  easy.
    B. Native: You can build native mobile apps with strategies using Ionic Framework, NativeScript, and React Native. Join our Best Flutter Course and become a proficient mobile app developer with in-demand skills.
   C. Desktop: Create desktop-installed apps across Mac, Windows, and Linux using the same Angular methods you’ve learned for the web plus.

2. Speed and Performance
   A. 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.
   B. Universal: You can use any technology with Angular for serving the application like node.js, .NET, PHP and other servers
   C. Code splitting: Angular apps load quickly with the new Component Router, which delivers automatic code-splitting, so users only load code required to render the view they request.

3. Productivity
   A. Templates: Quickly create UI views with simple and powerful template syntax.
   B. Angular CLI: Command-line tools: You can easily and quickly start building components, adding components, testing them, and then, instantly deploy them using Angular CLI.
   C. IDEs: Get intelligent code completion, instant errors, and other feedback in popular editors and IDEs like Microsoft’s VS Code.

4. Testing: With the Jasmine test framework, the Angular CLI downloads and installs everything required for testing your application. When you run ng test command, the app will be built in watch mode and the Karma test runner will be launched. Once that is done, you will see the output in the terminal plus, the chrome browser will open up showing the output in Jasmine HTML Reporter.
