When should I use sessionStorage in my web applications?

What is sessionStorage and when should I use it?

SessionStorage is a web storage API that allows you to store data for the duration of a page session. You should use it when you need to store data temporarily, like user preferences or form data, that should not persist after the tab is closed.

Can you give me an example of when to use sessionStorage?

Sure! If a user fills out a multi-step form, you can use sessionStorage to save their progress. If they accidentally refresh the page, their data will still be there until they close the tab.

Is sessionStorage secure for sensitive information?

No, sessionStorage is not secure for sensitive information. Data stored in sessionStorage can be accessed by any script running on the page, so avoid storing passwords or personal data.

How does sessionStorage differ from localStorage?

The main difference is the duration of data storage. sessionStorage lasts only for the duration of the page session, while localStorage persists even after the browser is closed.
