Angular Interview Questions For Experience

AngularJS is a JavaScript-based open-source front-end web application framework that is widely used for building dynamic and interactive web applications. Understanding AngularJS concepts and features is crucial for freshers preparing for an interview.. Here are some common Angular interview questions for Experience:

What is AngularJS?

AngularJS is a JavaScript framework developed by Google for building dynamic web applications. It allows developers to extend HTML syntax and build reusable components.

What are the key features of AngularJS?

• Two-way data binding
• Directives for extending HTML functionality
• Dependency injection
• Templating
• MVC (Model-View-Controller) architecture

Explain two-way data binding in AngularJS.

• Two-way data binding automatically synchronizes data between the model and the view. When you make changes to either the view or the model, I immediately reflected them in each other through two-way data binding.

What are directives in AngularJS?

• Directives are markers on DOM elements that attach special behaviors to them. You can create your own HTML elements, attributes, and classes to make reusable components and improve HTML..

Explain dependency injection in AngularJS.

• Dependency injection is a design pattern used to manage the dependencies of an object. In AngularJS, it allows you to inject the dependencies required by a component rather than creating them manually. This promotes code reusability and testability.

What is the difference between ng-show and ng-if directives?

• The ng-show directive toggles the visibility of an element by adding or removing the CSS property “display: none.” The element is always present in the DOM, just hidden.

• The ng-if directive completely removes or recreates the element based on the condition. If the condition is false, I removed the element from the DOM.

What is the difference between $scope and $rootScope?

• $scope is a scope object that refers to the application model. It is used within controllers, directives, and services to share data and functions.
• $rootScope is the parent scope of all $scope objects. It is accessible throughout the application and can be used to share data between different scopes.

What is AngularJS digest cycle?

• The digest cycle is a mechanism in AngularJS that detects changes in the model and updates the view accordingly. AngularJS checks watched properties and updates bindings during the digest cycle..

What is AngularJS routing?

• AngularJS routing allows you to define routes for different URLs in your application. It enables the loading of different views and controllers based on the URL, providing a seamless navigation experience.

Explain the concept of services in AngularJS.

• Services in AngularJS are singleton objects that are used to organize and share code across the application. They provide a way to separate business logic from controllers and make it reusable.

Remember, these are just a few examples of Angular interview questions for freshers. It’s essential to have a solid understanding of the AngularJS framework, its core concepts, and its ecosystem to perform well in an interview. To deepen your knowledge, practice coding and study AngularJS documentation.
