What can result from improper management of event handlers?

Improper management of event handlers can lead to potential memory leaks and performance issues because event handlers that are not properly removed when they are no longer needed can cause references to be held onto longer than necessary. This occurs when these handlers remain in memory even after the associated elements have been removed from the DOM or the objects they were attached to are no longer in use. As a result, not only does the application consume more memory over time, leading to slower performance, but it can also lead to an increase in processing overhead due to unnecessary event listeners being triggered.

Additionally, performance issues may arise as event triggers accumulate over time, causing the application to respond slowly or become unresponsive during interactions. This can significantly degrade the user experience, negatively impacting how users interact with the application. Therefore, proper management ensures that memory is allocated efficiently, and responsiveness remains optimal.
