A Detailed Overview of Angular Technology

A Google developed web application framework, Angular JS is a JavaScript-based open source framework specified for front-end web application. The basic purpose of developing Angular JS framework was to rectify development issues that occur during single-page applications.

It is specifically required to develop cross-platform mobile apps, simplifying the testing and development procedure. The biggest highlight of this framework is the client-side (MVC) model view controller along with (MVVM) model view ViewModel architectures.

A brief history of Angular JS-

Angular JS development started in the year 2008 when a developer of Google named Misko Hevery simplified the web app development structure. The sole purpose of coming up with Angular JS is to let designers expand their HTML knowledge helping static web server build a simple yet dynamic web application. The reason behind naming this technology ‘Angular’ was the presence of angular brackets within the HTML code frame.

How does it work?

This framework basically starts with HTML page interface showcasing multiple custom tag attributes. Angular displays the user attributes as directives in order, to sum up the input & output sections of a page model which is often represented using JavaScript variables. The multiple values of JavaScript variables can be amended manually, as per convenience.

Here is a functionality map giving you a better overview of coding structure of Angular JS-

Interface elements

Basic Widgets, Buttons, Bars, text fields

Compound Widget trees, grids, gauges

Visualization charts, infographics

Containers & Windows panels, cards and modals



View System

Layout Manager absolute, flex

Interactions gestures,

drag & drop

Drawing vector, bitmap

Theming computed styles

Templating iterations, conditionals

Visual effects animations, filters

Localization RTL, locate support

Accessibility focus manager ARIA

Logic & Data

State Manger history, routes

Data binding 1-way, 2-way

Modularity components, modules

Testing IOC, test hooks

Data Objects queues, hash tables

Data models & Stores group, sort, validate

Persistent Data extension

Multimedia 3D audio, video

Server i/o

Server calls asynch, conversion

Server Method Invocation

Sockets extension

Server Notifications

Support key

None/HTML 5



Angular JS-

Angular JS acts as one medium representing the declarative programming on a vast platform and signifying it as the necessity to build a stronger user interface connecting with multiple software components. It’s dynamic framework easily indulges and transform the ordinary HTML format into a two-way-binding process permitting the synchronization of both views and models.

The major goals of static Angular JS are-

  1. To segregate DOM manipulation from the actual application logic, as it can adversely affect the overall code structure in no time. 
  2. To segregate the server end and client end interfaces allowing customization on both the ends.
  3. To proffer a static structure or code path for the application development process which may include- designing and writing the required business logic.

The role of bootstrap in Angular JS-

The actual functionality of bootstrap starts only once DOM has been loaded successfully. After this, the developer is supposed to launch the Angular JS bootstrapper where a string of functions take place including-

1. Linking directives to the respective pages

2. Directives compilation which enhances the DOM

3. Creating a new injector

What is the actual two-way binding process in Angular JS?

One of the biggest highlights of overall Angular JS, two-way binding process is a recognizable approach which relieves the developer in terms of handling the server backend and other templating responsibilities. It helps to rectify minor or major issues available in the overall code structure and helps to modify the HTML in the view format using a controller. Apart from this, under the two-way binding, Angular JS analysis the changes occurring in the models and then run a comparison between the current values and the previously stored ones.

Here is a detailed table explaining the difference between Angular JS 1 and Angular JS-

What is new in Angular JS?

After the first-ever Angular JS, Google came up with Angular 2+ version which was an improvised write-up of Angular JS. This was basically more of a TypeScript completely based on open source front-end web app development and interface. Understanding, it's leveraged, on 13th December 2016, Angular 4 was declared and officially was launched in March 2017. Throughout this process, the string of number was disturbed and 3rd version of Angular was skipped just to avoid misalignment of the router packages which were disturbed in V3.3.0.

With an aim of bringing more dynamic interface development, on 1st November 2017, Angular 5 was launched. The major benefits or sole purpose of launching the 5th version was to simplify the programming structure of mobile apps and to improvise the material design overview of an application. Persisting the same, later on, 3rd May 2018 Angular 6 was launched and the most recent one is Angular 7 which came in the development industry on September/October 2018.

What is Angular Dart?

The Angular Dart is present within the Angular JS framework and it only works on Dart.  It is basically an object-oriented programming language having a class defined and single inheritance. It works on the principles of C# style syntax which is completely different from Angular JS.
