So , Today i started to explore the top-most question that always stuck our mind when we start with new technology . Like i already know my stuff then when i started with angular these above are basic questions that stuck my mind that what is angularjs and why i should use it and when  .

Today briefly I am going to give answers to these questions -

What is AngularJS ?

AngularJS is a javascript framework developed by Google's Employees . What so special about angularjs is it is client side . what all you need is Javascript and any programming language of your own choice to start with AngularJS that makes angular best . Like in my case I am Asp.net C# developer so I use my all logic like database connectivity in c# and all bindings are done by Angularjs and Let me tell you it is so fast in case of Searching and other type of operations required in Applications developement this is because everything in here is through javascript which is client side It has all inbuilt functions for different type of work that make it suitable for web development .

Why Its Called AngularJS ?

Now foremost question is why its called AngularJS this is because its main Namespace is ng and that sounds like Angular and JS is used with it that's why its called AngularJS .

Why To Use AngularJS

5 Main Points Why we should use AngularJS -

1. Angular Provides Data-Binding:- binding is the coolest concept in AngularJS. It's a fascinating real-time concept. Just like desktop application, mobile apps user also wishes to witness swift changes in the UI. So AngularJS’ two-way data binding handles the synchronization between the DOM and the model, and vice versa. As a result, the UI changes based on other input components are very much smooth without any extra effort on the part of the developer
2. Angular Enables Single Page Apps :- Single Page Applications are becoming more popular for a good reason. They fill a very specific need. More functionality is being moved to the web, and the browser is finally realizing its potential as a distributed computing node. By design, SPA applications are far more responsive (even though some of that is perception). They can provide an experience that feels almost like a native app in the web. By rendering on the client they cut down load on the server as well as reduce network traffic – instead of sending a full page of markup, you can send a payload of data and turn it into markup at the client. Of course, Angular doesn't force you into building a SPA app, it only provides plenty of built-in support
3.  Angular Provides Dependency Injection :- AngularJS has a built-in dependency injection subsystem useful for developers as it makes application development easier including testing. Dependency Injection (DI) allows users to ask for dependencies, rather than having to go and look for them or make them on their own .
   
   for example, “Hey I need X’, and the DI is responsible for creating and providing it for you. If user wants to gain access to core AngularJS services, all they need to do is add service as a parameter. AngularJS will detect that users need that service and will provide it instantly.
4.  AngularJS Directives :- Directives can create custom HTML tags that serve as new and custom widgets.Directives achieve this by allowing users to invent their own HTML elements. Putting DOM manipulation code into the directives makes it easy for the users to separate them out of MVC app and leaves MVC to update the view with new data, but how the view will behave is certainly up to directives
5. AngularJS requires less coding :- The data-binding feature allows developers to stop providing data manually into the view. Filters allow you to manipulate the data on the view level without changing your controllers. As a result, developers need to write very little code to achieve the task, which is a great deal for the developers
   
   

    When To Use AngularJS ?

   AngularJS is a very good SPA framework. If we want to create a SPA application, then AngularJS is a good option for it.“SPA” refers to Single Page Application. A Single Page Application is one in which we have a shell page and we can load multiple views into that. So a traditional app, as you know you typically blink and load everything again.
   It’s not very efficient on the bandwidth, especially in the mobile world. In a SPA, we can load the initial content upfront and then the different views or the small kind of mini web pages can be loaded on the fly and embedded into the shell.
