  One way to check if an element has a class related to digital currencies using jQuery is by using the `hasClass()` function. You can pass the class name as an argument to the function and it will return true if the element has the class, and false otherwise. For example, you can use the following code: ```javascript if ($('#elementId').hasClass('digital-currencies')) { // The element has the class related to digital currencies } else { // The element does not have the class } ```

  To check if an element has a class related to digital currencies using jQuery, you can also use the `is()` function. This function allows you to check if an element matches a selector or a set of elements. You can pass the class name as a selector to the function and it will return true if the element has the class, and false otherwise. Here's an example: ```javascript if ($('#elementId').is('.digital-currencies')) { // The element has the class related to digital currencies } else { // The element does not have the class } ```

  Another way to check if an element has a class related to digital currencies using jQuery is by using the `attr()` function. This function allows you to get the value of an attribute for the first element in the set of matched elements. You can use it to check if the element has the class by getting the value of the `class` attribute and then using the `indexOf()` function to check if it contains the class name. Here's an example: ```javascript var classValue = $('#elementId').attr('class'); if (classValue.indexOf('digital-currencies') !== -1) { // The element has the class related to digital currencies } else { // The element does not have the class } ```

  If you want to check if an element has a class related to digital currencies using jQuery, you can also use the `hasClass()` function combined with the `toggleClass()` function. The `toggleClass()` function adds or removes one or more classes from the selected elements. You can use it to add a temporary class to the element and then check if it has been added using the `hasClass()` function. Here's an example: ```javascript $('#elementId').toggleClass('temp-class'); if ($('#elementId').hasClass('temp-class')) { // The element has the class related to digital currencies $('#elementId').removeClass('temp-class'); } else { // The element does not have the class } ```
