What is a common characteristic of Client Variables?

Client variables are designed to store data specific to a user session, and one of their defining characteristics is that they persist across different sessions for each user. This means that once a client variable is set, it retains its value even after the user navigates away from the application and returns later. This persistence is vital for enhancing user experience, allowing applications to remember user preferences, inputs, or states across multiple interactions.

In apps where user-specific information is crucial, the capability of client variables to maintain data continuity is essential. This aspect distinguishes them from other types of variables that may only hold temporary or shared information.
