What is the primary purpose of the cleanup phase in a webpage lifecycle?

The primary purpose of the cleanup phase in a webpage lifecycle is to release resources and reset variables. During this phase, any resources that were allocated during the execution of the webpage (such as memory, file handles, or network connections) are freed. This is crucial for preventing memory leaks, which can degrade performance over time by consuming system resources unnecessarily.

Additionally, resetting variables helps ensure that the next time the webpage is loaded, it starts with a clean state, thereby avoiding any unintended side effects from previous interactions. This phase contributes to the overall efficiency and stability of web applications, allowing them to run smoothly by efficiently managing system resources and preparing for new user sessions.

While user preferences, logging, and server uptime are important aspects of a web application's operation, they are not the primary focus of the cleanup phase, which is specifically aimed at resource management and state resetting.
