Should I use cookies or sessionStorage?

When should I use sessionStorage?

Session storage is a popular choice when it comes to storing data on a browser. It enables developers to save and retrieve different values. Unlike local storage, session storage only keeps data for a particular session. The data is cleared once the user closes the browser window.

Local storage can store up to 5mb offline data, whereas session can also store up to 5 mb data. But cookies can store only 4kb data in text format.

Which is better sessionStorage vs localStorage?

The difference between sessionStorage and localStorage is that localStorage data does not expire, whereas sessionStorage data is cleared when the page session ends. A unique page session gets created once a document is loaded in a browser tab. Page sessions are valid for only one tab at a time.
