What is sessionStorage and how is it different from localStorage?
sessionStorage is a web storage object that allows you to store data for the duration of the page session. Unlike localStorage, which persists even after the browser is closed, sessionStorage data is cleared when the page session ends.
Can you give me an example of how to use sessionStorage in JavaScript?
Sure! You can use sessionStorage like this: sessionStorage.setItem('key', 'value');
to store data, and sessionStorage.getItem('key');
to retrieve it.
Is there a limit to how much data I can store in sessionStorage?
Yes, most browsers limit sessionStorage to about 5-10MB per origin, but this can vary.
When should I use sessionStorage instead of cookies?
Use sessionStorage for temporary data that only needs to last for a single session, while cookies are better for data that needs to persist across sessions.
