Introduction to Angular Js

AngularJs is an open-source Javascript front-end framework that is mostly used to create single-page web apps (SPAs). It's a framework that's always evolving and improving, allowing for more efficient web application development. Dynamic HTML takes the role of static HTML. Its characteristics, like as dynamic binding and dependency injection, eliminate the need for us to create code. Because AngularJs is continually evolving, we have a variety of versions, the most recent of which is 1.7.7. It's also worth noting that Angular and AngularJs are not the same things. Anyone can use and modify it because it is an open-source project. Data is coupled with HTML, and it extends HTML attributes with Directives.

General features

AngularJS has the following general features:

  • AngularJS is a powerful framework for building RPAs (RIA).
  • Developers can use AngularJS to create clean Model View Controller (MVC) client-side apps using JavaScript.
  • Cross-browser compatibility is a feature of AngularJS apps. AngularJS manages JavaScript code that is appropriate for each browser automatically.
  • AngularJS is an open-source framework that is free to use and is utilised by thousands of developers worldwide. It's under the Apache 2.0 licence.
  • AngularJS is a framework for creating large-scale, high-performance, and simple-to-maintain web applications.

    Freshers - Angular Js Interview Questions and Answers

    In AngularJS, scopes are special objects that serve as a link between the view and the controller. They're talking about the MVC architecture's model component. To replicate the DOM structural hierarchy, they're organised in a hierarchical order. All of the application data and associated methods are bound to the $scope object in AngularJS

    Directives are the most significant AngularJS elements because they represent DOM element markers that provide new functionality to DOM elements such as names, attributes, CSS classes, and comments. They're used to make custom HTML tags that work in the same way that custom widgets do. AngularJS has directives like ng-model for data binding, ng-repeat for iterating components, ng-app for bootstrapping AngularJS apps, and ng-show, ng-hide for controlling the appearance of DOM elements, among others.

    Single objects called services perform the duties for which they will establish. They are communicated and connected via the Dependency Injection principle, which aids the framework in structuring and sharing code across the application. AngularJS comes with a variety of built-in services. AngularJS also allows developers to build bespoke services.

    Interpolation is the process of attaching data to attribute and text nodes by embedding expressions. During the compilation of the process, the compiler is in charge of matching text and characteristics. Internally, AngularJS checks for embedded expression in markups using the $interpolate built-in service, and if they found, they are updated and registered as watches.

    Each AngularJS application has one $rootScope object and multiple child $scope objects. The parent scope is updated whenever a new scope is formed. As a result, a hierarchical structure similar to the DOM structure was created.
