How does sessionStorage compare to localStorage in terms of performance?

How does sessionStorage compare to localStorage in terms of performance?

SessionStorage and localStorage both use the same underlying storage mechanism, but sessionStorage is generally faster for short-term data access because it only lasts for the duration of the page session.

Are there any limitations to using sessionStorage?

Yes, sessionStorage has a size limit (typically around 5MB) and is only accessible within the same tab or window. Once the tab is closed, the data is lost.

When should I use sessionStorage instead of localStorage?

Use sessionStorage when you need to store data temporarily for a single session, like user input in a form, while localStorage is better for persistent data.

Can sessionStorage be shared across tabs?

No, sessionStorage is unique to each tab or window. If you open a new tab, it will not have access to the sessionStorage of the original tab.

What are some best practices for using sessionStorage?

Some best practices include keeping data minimal, using clear keys for easy retrieval, and ensuring sensitive data is not stored.
