This AngularJS tutorial also includes practical use cases of AngularJS. This AngularJS is your first step to learning AngularJS.

This technology has gained immense popularity because of the following reasons:

  • AngularJS applications are supported by different browsers
  • Uses data-binding for providing synchronization between model and view layers
  • Incorporates the concepts of various languages including JavaScript and server-side languages.

What is AngularJs?

AngularJS is a JavaScript framework used in developing single-page web applications.It is considered to be a preferred framework because it can be easily added to HTML pages with simply a <script> tag. It is also known for one of its exclusive features, i.e. Angular.js converts the static HTML to dynamic HTML and also offers dynamic binding.It has consistently evolved and is currently known for offering much more advanced ways to develop better web applications.

Angular.js is an open-source front-end framework because of which is why it is also a preferred tool for the majority of Front-end web developers. Also, since we are talking about Angular.js, it needs to be noted that it is different from Angular.

AngularJS History

The birth year of AngularJS was 2010. It was originally developed by Miško Hevery at Brat Tech LLC. The framework was created as the software behind an online JSON storage service for easy-to-make applications for the enterprise.

The creation of AngularJS actually started in the year 2009, when Miško Hevery was working on a part-time project to simplify the web development process. He created the AngularJS framework so that there can be a static web server that will help in building simple web applications. Now, Adam Abrons, who was Miško Hevery’s friend, was also working on this project. He named it Angular because it uses HTML and HTML consists of angular brackets.

AngularJS Example

Let us start by understanding how a script looks like in AngularJS. Have a look at the following sample script:


Example of AngularJS

Given below is a sample of AngularJS.

<!DOCTYPE html>
<script src=""></script>
<div ng-app="">
<p>Name: <input type="text" ng-model="name"></p>
<p ng-bind="name"></p>

Angular History

Angular was created by two developers named Adam Abrons and Misko Hevery as a side project. They envisioned the project GetAngular with an aim to simplify web development and allow web designers to interact with both backend and frontend. Misko Hevery was a developer at Google, while Adam Abrons who was working with Hevery on a Google project, named angular after HTML as  HTML contains angular brackets.

Hevery was working on a Google project named Google Feedback with two more developers in the team. Over 6 months, they’ve written 17000 lines of code. However, with the increased code size, it became very difficult to modify and test the code which the team has written. So, Henry bet his manager that he can write the entire project with his side project in just two weeks.

He lost the bet and took three weeks to finish writing the code, but he was able to squeeze the 17000 lines code down to 1500. His manager took notice of his achievement and the development of Angular.js began to accelerate.

Why Angular?

Angular is one of the most popular JavaScript-based web development frameworks and is used by many software engineers to create web applications. According to the Stack-Overflow developers survey from 2017, more than 44% of web designers and developers use Angular for creating user interfaces. But why is Angular so popular? Well, below are some of the reasons why is it so:

  • Angular apps are built using the TypweScript language, which eliminates the errors while writing the codes and ensures high performance and security.
  • Provides two-way binding that provides a seamless synchronization between the modes and the view. It updates these components in real-time, in case the data is modified.
  • The time investment in Angular for the projects is less as compared to other web development frameworks. The Angular CLI tool allows the developers to create initial projects, perform testing, and integrate features in the same.
  • The Angular view engine takes templates you’ve written and compiles them into HTML and JavaScript files so that the browser can read them.
  • Reduce development time as Angular uses HTML to define the User-interface of an application, which is less complex as compared to JavaScript.

How is AngularJS better than jQuery?

This is quite a common comparison while jQuery is a DOM manipulation library that uses JavaScript, AngularJS is a JavaScript framework designed to generate SPAs for web development. Both the technologies have gained immense popularity, but before opting for technology for web development the programmer should have a clear knowledge of these two concepts. Let’s get to know which technology should you opt for and when:

Criteria AngularJS jQuery
Built for Built  for Single Page Apps Built mainly for DOM Manipulation
Interactivity Provides a lot of interactivity Provides little interactivity
Structure Has a framework No structure

Versions of AngularJS

AngularJS was the first to be released in the year 2010. It is hence also kown as Angular 1X or the first version of Angular. Later, Angular2.0 was introduced in 2016 with a new additional feature, i.e. mobile oriented. In April 2015, the developers moved angularly from the alpha to the developer’s preview and launched a beta version in December 2015.

Angular 3 was skipped due to some confusion and Angular 4 was released in the year 2017.

It was smaller in size and came with additional features like HttpClient and also supported conditionally disabled animations. Angular 5 was released at the end of 2017 with a minor update.

The next version, Angular 6 was released on May 4th, 2018. It came with major updates and features like CLI workspace, library support, ng add, ng update, Angular material starter components, Angular element, etc. However, Angular 7 was released in October 2018 which improved both the performance and efficiency of the framework.

Following the trend, Angular 8 was released in May 2019, Angular 9 in February 2010, Angular 10 in June 2020, and Angular 11 in November 2020, which is the latest version of Angular.

Features of AngularJS

There are many features responsible for the popularity of AngularJS as a framework for Software Development. We have mentioned below some of the main features:

  • User Interface

AngularJS builds the user interfaces on HTML, which becomes easy to comprehend as HTML is a declarative language. Also, because of this, the user interfaces in AngularJS are properly structured, robust and smooth. The HTML based user interface helps in regulating efficient implementation of the web application too.

  • Built on POJO Model

The POJO model simply means – Plain Old JavaScript Objects. AngularJS is based on the POJO model which implies that no additional elements or components need to be added to integrate AngularJS with other data sources.

  • Easy Routing

Routing means transition from one view or page to another. Usually one of the difficulties faced with single page applications is that every time the user clicks on a sub category, it reroutes him to a separate view. This is one of the difficulties that web developers face. But AngularJS makes the routing easier by letting web developers create various views for various URLs.

  • Two-Way Binding

AngularJS allows web developers to create templates that allow ease in binding different components with various models. This is an important feature offered by AngularJS because whenever the values of an HTML or view component vary or are changed, the model that is bound with it also gets automatically adjusted or updated.

Getting Started with AngularJS

AngularJS is used to build single-page applications and features with declarative templates. The developers can build the applications and reuse the code to build other applications. AngularJS has a learning curve similar to a hockey stick, which means starting with the framework is easy. However, building complex applications require more effort and understanding of AngularJS’  framework.

Now, Let’s check the prerequisites to install and start using the Angular framework:

Prerequisites for Angular

Before starting with Angular, it’s better if you have sound knowledge of the following concepts and languages:

  • Knowledge of HTML, CSS, and JavaScript
  • JavaScript functions, error handling, and events
  • Basic knowledge of the Document Object Model(DOM)
  • Model-View-Controller(MVC) concepts
  • Knowledge of Node JS and Node Package Manager(npm)
  • Angular CLI
  • Libraries such as Rx and JS
  • Error handling

System Requirements

  • Windows 10 or similar Operating System
  • At least 10GB of free storage space
  • Minimum 4GB of RAM
  • An editor like VSCode to write ad edit your codes
  • Node JS version 8 or 10, pre-installed in your system. You can check the Node.js version using the node -v command

Step-1: Installing Angular CLI

You can install Angular CLI using the console/terminal window by entering the following command:

Npm install -g @angular/cli

The angular CLI is used to create library codes, projects, and applications and perform various tasks like testing, bundling, and deploying the applications. You can verify the version of your Angular CLI with the ng –version command.

Step-2: Create a workspace

An angular workspace contains the files, codes, libraries, and projects. To create a new workspace, type in the following statement in the CLI command:

ng new my-app

This command ng new installs all the necessary packages, files, and dependencies and creates a workspace by the name ‘my-app.’ In this workspace, the following project files are created:

  • Root folder names my-app
  • Skeleton project in the src directory
  • End-to-end test project
  • Other configuration files

The workspace contains the initial project with a welcome application. Now, you’re ready to create your first Angular component and serve the application.
