Why Angular JS and what is difference between Angular JS and JQuery?

Hello Vakeel 

Great queston , it might be a litlle confusing but they are both built on top of  Javascript . Jquery is a JS library meant to let you do more with less code .wheras angular is a framwork that makes bulding web applications  very easy . If you are bulding a single page web app you should go with Angular or React JS . if you are just adding interactivity to your websites you can stick with Jquery . 

I hope that helped :)

Angularjs is front end javascript framework enable us to build single page front end application, Jquery is front end javascript library and it simplify to manipulate DOM.

AngularJS : AngularJS is for developing heavy web applications. AngularJS can use jQuery if it’s present in the web-app when the application is being bootstrapped. If it's not present in the script path, then AngularJS falls back to its own implementation of the subset of jQuery.

JQuery : jQuery is a small, fast, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler. jQuery simplifies a lot of the complicated things from JavaScript, like AJAX calls and DOM manipulation

I was discussing this yesterday with my colleague.

the simple answer is :

JQuery : Library, used for the display of the html page.AngualrJS:Frame work, used for handeling data of the html page.

i.e.

JQuery: Display. Library.

AngualrJS: Data. Framework.
