Bootstrap 4 Vs ng-Bootstrap in AngularJs 2 ?
Bootstrap is an opensource responsive css framework developed and maintained by twitter and bootstrap 4 now came up with lot of enhancements, utility classes and even increase one more media query for a better design across the devices.
Why we need ng-Bootstrap ?
As like bootstrap angularjs is also an opensource mvc javascript framework by google to achieve the MVC concepts with javascript itself which greatly reduce the involvement of the programming languages like php or jsf or jsp(still we need, but reduced in angularjs comparing with jquery).
When you are planning to integrate bootstrap with angularjs then it’s really a tough one because of the jQuery dependency. angularjs is designed purely with javascript and without jQuery. Sametime bootstrap 4 is completely dependent on jQuery.
So ng-bootstrap came into the picture to overcome this issue, basically ng-bootstrap removed all the jquery dependencies to support angularjs by making the javascript support completely.
Thing to Note:
You can still use the bootstrap 4 with angularjs which will not create any issue, but its really poor way of using angularjs.
