In JMeter, BeanShell Listener is a scripting-based listener. It means that you will need to implement the listener logic by yourself using one of the supported scripting languages. Usually, it is helpful when you need to define logic based on your requirement and want to write some unique algorithm which is not currently provided by JMeter. You can create your own implementation of the algorithm using BeanShell listener.
