Key Concepts in AngularJS
1. MVC Architecture
AngularJS follows the Model-View-Controller (MVC) architectural pattern, which divides the application logic into three interconnected components:
- Model: Represents the data and business logic.
- View: Handles the presentation and user interface.
- Controller: Manages communication between the Model and the View.
2. Two-Way Data Binding
One of AngularJS’s standout features is its two-way data binding. Changes in the user interface automatically update the underlying data model and vice versa. This simplifies data synchronization between the view and the model, reducing the need for manual manipulation.
3. Directives
Directives are markers in the DOM that instruct AngularJS to attach specific behavior to a DOM element or transform the DOM’s structure. They enhance HTML with new functionalities and enable the creation of reusable components. Common directives include ng-model
, ng-repeat
, and ng-if
.
4. Services
AngularJS provides a set of built-in services that offer common functionalities, such as HTTP requests, routing, and more. Developers can also create custom services to encapsulate specific features and share them across different components.
5. Dependency Injection
Dependency Injection (DI) is a design pattern used in AngularJS, allowing components to be loosely coupled. This enhances modularity and simplifies testing.
AngularJS Tutorial
AngularJS is a free and open-source JavaScript framework that helps developers build modern web applications. It extends HTML with new attributes and it is perfect for single-page applications (SPAs).
AngularJS, developed by Google, has been important in web development since its inception in 2009. AngularJS excels at building SPAs. These are applications that load in the browser once and update content without needing to refresh the entire page, providing a smoother user experience.
This AngularJS tutorial is designed to learn AngularJS quickly and efficiently. You will start by learning the fundamentals of AngularJS, including directives, expressions, filters, modules, and controllers. After that, you will learn about a variety of other aspects of AngularJS, such as events, DOM, forms, input, validation, HTTP, and more.
Additionally, we also provide AngularJS interview questions to help you deepen your understanding of the framework and prepare for potential job opportunities.
