What are the advantages and disadvantages of using JavaScript libraries like jQuery for handling asynchronous form submissions in PHP applications?

When handling asynchronous form submissions in PHP applications, using JavaScript libraries like jQuery can simplify the process by allowing for seamless communication between the front-end and back-end. This can result in a more responsive user experience and reduce the need for page reloads. However, relying on external libraries can also introduce dependencies and potential performance issues.
