jQuery is a front-end library that is handy for modern web developers. It provides a series of easy-to-use JavaScript functions and methods that can be used to quickly develop dynamic web applications. One of the most useful features is classes, which allow developers to easily handle classes of DOM elements.

However, as time goes by, jQuery’s API and functions continue to evolve. In this article, we’ll explore jQuery’s class-related features and what they don’t include.

First of all, we need to understand what the class of a DOM element is. In web development, HTML elements can contain one or more CSS classes, which define the appearance and behavior of the element. By using jQuery's class-related functions, developers can easily add, remove, and switch classes for elements.

For example, to add an element to the CSS class "active", you can do it with the following code:

$('#my-element').addClass('active');

By using the addClass function, jQuery will add an element with the ID "my-element" Add a CSS class called "active" to the element.

In addition, jQuery also provides the removeClass function and toggleClass function to remove CSS classes from DOM elements or toggle them respectively.

However, jQuery’s class function does not include some other functions. First, it does not include Cross-Origin Resource Sharing (CORS) functionality. CORS is a protocol that allows web pages to request resources from different domain names and ports. Although jQuery provides some AJAX-related functions, its class functions have nothing to do with CORS.

In addition, jQuery’s class function does not include a JavaScript module loader. A module loader is a tool that allows web developers to organize their code and load it when needed. Although not all web applications require a module loader, jQuery does not have any features related to it.

Finally, jQuery’s class function does not include Web Components specifications and related APIs. Web Components is a technology for creating custom HTML elements. Although they are not equivalent to regular HTML elements such as divs and spans, Web Components have become an important part of many modern web applications.

In summary, we can see that jQuery's class-related functions are a very useful web development tool. Although it does not include features such as CORS, JavaScript module loaders, and Web Components, it is still a powerful and convenient library for CSS classes that handle DOM elements.
