AngularJS Tutorial For Beginners

In the tutorial, we will learn about angular, including its features, applications, advantages, versions, etc. Currently, in the IT industry, most companies prefer the angular framework to manage the front end of their websites. It is a prevalent and demanding framework for the job purpose and the development of the front-end developer.

What is Angular?

Angular is a complete open-source front-end web application framework developed and maintained by Google. It is used to build a dynamic and single-page application (SPA) and is popular among developers for its features and scalability. It empowers developers to make fast and reliable applications.

The Single page application (SPA) is a web application that includes the features to load data and redirect one page (component) to another component without reloading the main page. It offers routing features that allow to setting of a route for a particular component and enables the features of SPA.

Application Developed Using AngularJS

Following are lists of applications developed through Angular Framework:

• Google Cloud Platform Console
• YouTube for PS3
• Upwork
• Nike
• PayPal
• Freelancer.com

What You Should Already Know?

Before start learning Angular you should know about the following frontend technologies that help you to better understand the Angular framework:

Why to Learn AngularJS?

Angular is a TypeScript-based front-end framework that is very user-friendly and allows developers to quickly build various types of front-end applications. TypeScript, a superset of JavaScript, enhances the language by adding static typing to variable declarations.

Following are some key points that tell you the reason why to learn Angular:

• Easy to Learn: Learning Angular is very easy due to its large community and the large number of available resources on various websites, including the official documentation.
• Free of Costs: Angular is freely available as an open-source framework, stopping the need for any financial investment to use its methods and services as compared to other languages and IDEs.
• Angular CLI: Angular's Command Line Interface (CLI) allows developers to manage packages and libraries such as Bootstrap, Angular Material, PrimeNG, JSON-Server, Components, Modules, and Services via simple command-line commands.
• TypedScript: Angular uses TypeScript, a statically typed superset of JavaScript, which enhances code quality and developer productivity.

Angular Features

Below are lists of features of the Angular framework:

• Routing: Angular supports routing features that allow developers to build single-page applications (SPAs) and manage individual components and modules efficiently. It helps to create a better user experience by navigating between different components (pages) without reloading the entire page.
• Mobile Support: Applications developed in an Angular framework are mobile-supportive.
• Angular CLI: The Angular Command Line Interface (CLI) simplifies the development process by creating tasks such as creating an angular application and installing package libraries, components, modules, services, etc through CLI.
• Design Patterns: Angular supports several design patterns such as Dependency Injection (DI) and Component-based architecture. These patterns enhance application performance by enabling code reusability, maintainability, and scalability.
• HTTP and RESTful Services: Angular provides built-in support for HTTP services, allowing applications to communicate with backend servers using RESTful APIs. It enables fetching and posting data asynchronously.
• Two-way Data Binding: Angular supports two-way data binding, which means, it changes in the model (data) are automatically reflected in the view (UI), and vice versa.
• Directives: Directives are features on a DOM element that tell Angular to attach a specific behavior to that element or transform the DOM structure. Angular provides several built-in directives such as ngIf, ngFor, and ngSwitch, and you can also create custom directives.

AngularJS Advantages

Below are lists of angular advantages:

• Modular Structure: It enables a modular structure for organizing your application into separate modules, making it easy to manage and scale large applications.
• Dependency Injection: Angular has a built-in dependency injection system that helps to make components and services more modular, reusable, and testable.
• Component-Based Architecture: Angular uses a component-based architecture, where UI is developed using components. It enables reusability, and maintainability helps in separating problems.
• Cross-platform Development: Using Angular, you can build web applications as well as native mobile applications using frameworks like Ionic.

AngularJS Versions

Angular has gone through several versions since when it was released for the first time. The framework's first version, AngularJS (1. x), was introduced in 2010 by Google. If we talk about version 2.0, the framework became simply "Angular," marking a complete rewrite and adoption of TypeScript language.

Following are the lists of Angular versions and their release year:
