Introduction to AngularJS

The primary driver behind the success of the internet is HTML (HyperText Markup Language) , created in 1990 by Sir Tim Berners-Lee – A famous British physics and computer scientist – while he was working at CERN . The motivation behind HTML, was the search for an optimum solution to share information among the researchers of the institution.  HTML also required HyperText Transfer Protocol (HTTP) and its first server which primarily gave rise to World Wide Web (WWW).

Initially HTML was used to create static documents with hyperlinks, allowing the navigation between them. However, in 1993, with the creation of Common Gateway Interface (CGI), it became possible to create dynamic content generated by server-side applications. One of the first languages for this purpose was Perl, followed by other languages like Java, PHP, Ruby and Python.

The intervening period between then and now, has seen a whole host of web based technologies come and go, caused primarily by what is known as the Browser Wars . However there has been a few consistent technologies that has survived i.e. JavaScript, HTML and CSS, and the popularity of the technologies has been steadily increasing over the years. Due primarily to how it enables a high level of user experience without using any proprietary plugins.

AngularJS is a new generation of libraries and frameworks developed to support productive, flexible, maintainable and testable web applications.

What is AngularJS ?

AngularJS was developed by Misko Hevery and Adam Abrons in 2009, as an Open Source, client-side JavaScript framework to promote high-productivity web development experiences.

Based on the belief that declarative programming is the best choice to construct the user interface, while imperative programming is much better and preferred to implement and applications business logic.  To Achieve this, AngularJS empowers the traditional HTML by extending its current vocabulary to make developers lives easier, providing expressive, reusable and maintainable application components.

Tutorial Objective

The objective of this tutorial is not necessarily to discuss all the finer points of Angular or to be a complete in depth guide, but rather more of a quick start guide.  I will provide just enough detail for you to get up to speed quickly and start developing with AngularJS in the minimal amount of time.  All lessons are based on what exactly I needed to know in order to start delivering my first few applications using angular.
