Dependency InjectionĪngular implements unidirectional tree-based change detection and uses the Hierarchical Dependency Injection system. Angular2 provides a better structure to more easily create and maintain big applications and a better change detection mechanism. However, by creating more processing on the client-side, page load was taking considerable time. Speedīy providing features like 2-way binding, AngularJS reduced the development effort and time. The later versions, Angular 2 and Angular 4, have been upgraded to provide an overall improvement in performance, especially in speed and dependency injection. Although there were a few evolutionary improvements in its design, they were not enough to fulfill developer requirements. RoutingĪngularJS uses $routeprovider.when() to configure routing while Angular uses PerformanceĪngularJS was originally developed for designers, not developers. Mobile SupportĪngularJS was not built with mobile support in mind, but Angular 2 and 4 both feature mobile support. Angular versionsĪngular focuses on “( )” for event binding and “” for property binding. To bind an image/property or an event with AngularJS, you have to remember the right ng directive. This has the combined advantages of the TypeScript features, like type declarations, and the benefits of ES6, like iterators and lambdas.Īngular 4 is compatible with the most recent versions of TypeScript that have powerful type checking and object-oriented features. Angular versionsĪngular uses Microsoft’s TypeScript language, which is a superset of ECMAScript 6 (ES6).
Language AngularJSĪngularJS is written in JavaScript. In Angular 4, the structural derivatives ngIf and ngFor have been improved, and you can use if/else design syntax in your templates. These are structural directives that alter the layout of the DOM by removing and replacing its elements, and attributive directives that change the behavior or appearance of a DOM element. They deal with a view of the application and logic on the page. There are two kinds of directives in Angular 2. Components are directives with a template. In Angular 2, controllers and $scope were replaced by components and directives. The controller accepts input, converts it into commands and sends the commands to the model and the view. The view generates an output based on the information in the model. The model is the central component that expresses the application’s behavior and manages its data, logic, and rules. The architecture of AngularJS is based on the model-view-controller (MVC) design.
We compare architecture, language, expression syntax, mobile support, and routing. Angular 4 is only an improvement and is backward compatible with Angular 2.ĭifference Between AngularJs and Angular Versionsīelow is a comparison of AngularJS to Angular, because Angular includes both version 2 and version 4. Although Angular 2 was a complete rewrite of AngularJS, there are no major differences between Angular 2 and Angular 4. Both Angular 2 and 4 are open-source, TypeScript-based front-end web application platforms. Is the blanket term used to refer to Angular 2, Angular 4 and all other versions that come after AngularJS. 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. Is an open-source, JavaScript-based, front-end web application framework for dynamic web app development.
