The **jQuery `hasClass()`** is a built-in method used to check whether the selected elements, with a specified class name, exist or not. `hasclass()` returns a boolean value. If a specified class is present in any of the selected elements, a `true` value is returned; otherwise, ​the method returns a `false` value. 

.red { color:red; }  
.bold { font-weight: bold;
 }
