What are the best practices for client-side storage?

When using client-side storage, consider these best practices: 1. Use localStorage for simple key-value pairs. 2. Use sessionStorage for temporary data. 3. Avoid storing sensitive information. 4. Implement data expiration strategies. 5. Regularly clear unused data.

Why should I avoid storing sensitive information?

Storing sensitive information like passwords or personal data in client-side storage can expose it to security risks, such as XSS attacks. It's safer to handle such data on the server side.

What is the difference between localStorage and sessionStorage?

localStorage persists data even after the browser is closed, while sessionStorage only keeps data for the duration of the page session. Use localStorage for long-term storage and sessionStorage for temporary data.

Can you give an example of data expiration strategies?

Sure! You can implement expiration by storing a timestamp along with your data and checking it before accessing the data. If the current time exceeds the stored timestamp, you can clear the data.
