Different between Angular and AngularJS

Definition

AngularJS is an open-source, JavaScript-based, front-end web application framework for dynamic web app development. It utilizes HTML as a template language. By extending HTML attributes with directives and binding data to HTML with expressions, AngularJS creates an environment that is readable, extraordinarily expressive, and quick to develop.

Angular 2 is the blanket term used to refer to Angular 2, Angular 4 and all other versions that come after AngularJS. Both Angular 2 and 4 are open-source, TypeScript-based front-end web application platforms.

Angular 4 is the latest version of Angular. Although Angular 2 was a complete rewrite of AngularJS, there are no major differences between Angular 2 and Angular 4. Angular 4 is only an improvement and is backward compatible with Angular 2.

Angular JS vs Angular

Angular uses TypeScript and has components as its main building blocks. It is component-based, whereas AngularJS uses directives.

Angular’s operation employs a hierarchy of components, while AngularJS has directives that allow code reusability. So, The AngularJS framework provides reusable components for its users.

Why Angular?

  • It has a mobile support framework.
  • The latest Angular version supports TypeScript and enables code optimization and modularity by employing the OOPS concept.
  • It supports the changes for an increased hierarchical dependencies system.
  • A developer can use various features such as syntax for type checking, Dart, TypeScript, ES5, iterators, Angular CLI, ES6, and lambda operators.
  • Angular opts for semantic versioning that has a major-minor-patch arrangement.
  • Amongst its best benefits is its provision for the event of simplest routing.

Why AngularJS?

  • It’s secure MVC (Model-View-Controller) data binding makes application performance dynamic.
  • A developer can easily perform unit testing or change detection at any point.
  • It provides several helpful features for web developers, like declarative template language with HTML to allow them to make it more intuitive.
  • The open-source framework allows well-structured front-end development. It doesn’t require any plugin or other platforms to work.
  • The AngularJS application runs on Android and iOS phones and tablets.
