n the “real world,” JQuery is often used in aesthetic and/or interactive ways. For example, the fadeIn function could be used to make the background color of a navigation bar fade to a lighter color when the user mouses over it. And the height and width functions can easily be used to restrict all elements of a certain class or id on a page to the same height and width specifications. It allows for pages to be changed and interacted with dynamically, and is especially useful for things like user menus and navigation bars. Buttons can also be made to look more interactive and stylish with the built-in functions that JQuery supplements. W
Overall, however, JQuery is a relatively easy-to-learn and interesting little language that can make some powerful aesthetic/interactive changes to a website.
