Jquey-ui depends on Jquery

Question

Does jquery-ui depend on jquery in an application ? , I ask because in the application I am working apparently jquery.min is not being used, and the doubt and if it has to be there to support jquery-ui.

Thanks in advance, thank you.

Answer 1

Yes, totally dependent on jQuery:

"jQuery UI is a curated set of user interface interactions, effects, widgets and themes built on the jQuery Javascript library". source

---

jQuery UI is a collection of GUI widgets, animated visual effects and themes implemented with jQuery (a Javascript library ), Cascading Style Sheets and HTML . source

---

jQuery UI is an interaction tool and built above the core of jQuery that allows you to animate the different HTML elements. source

---

Totally based on the framework¹ jQuery, is used to provide a better interaction between user and client (web browser), with rich features like animation, effects, stylizable components, etc. source

EXAMPLE: note in both lines script as first is loaded to jQuery and then to jQuery UI and that if you remove the line that matters to jQuery the example does not work:

$( function() {
   $("#draggable").draggable();
});

#draggable { 
  width: 150px; height: 150px; padding: 0.5em; background-color:blue; color:#FFF;
}

<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
 
<div id="draggable" class="ui-widget-content">
  <p>Drag me around</p>
</div>

Note 1: Although in the text the word appears Framework referring to jQuery, it is not considered as such, but rather as a library. Know the difference here

Note 2: Strange your code doesn’t present dependency on jQuery, because as we saw the jQuery UI is totally dependent on the same.
