Ques:- How to access jQLite or jQuery with AngularJS?

Asked In :- Hidden Brains InfoTech, iks,

Right Answer:
In AngularJS, you can access jQLite using the built-in `$` function, which is available in the scope of AngularJS. If you want to use jQuery instead, you need to include the jQuery library in your project and then you can use the `$` function as well, as AngularJS will use jQuery if it is present.

Ques:- How to use jQuery with AngularJS?

Asked In :-

Right Answer:
To use jQuery with AngularJS, you can include the jQuery library in your project and then use jQuery functions within AngularJS controllers, directives, or services.
