Avinash is correct that the Widgets framework will use jQuery and force it to load on the page.  The control panel will also force jQuery to be rendered on the page.  However, you should never rely on someone else to request jQuery for you because you can never be certain when the admin might turn off or remove the other feature or module.  Instead, the best practice is that if your module uses jQuery, then you should always request registration.  This will guarantee that you will always have jQuery on the page when you need it.

Hi Eduard,

Better you always request registration when your module uses jQuery as Joe Brinkman said.
