What are the limitations of web storage APIs?

Web storage APIs, like localStorage and sessionStorage, have several limitations. They typically have a storage limit of about 5-10MB per origin, are synchronous, and can only store string data. Additionally, they are not suitable for large datasets or complex data structures.

Why is there a storage limit?

The storage limit is primarily in place to prevent abuse and ensure that web applications do not consume excessive resources on users' devices. It also helps maintain performance and security.

Can I store objects in web storage?

You cannot store objects directly in web storage, but you can convert them to strings using JSON.stringify() before storing and then parse them back with JSON.parse() when retrieving.

What are the differences 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. This means localStorage is available across tabs and windows, whereas sessionStorage is limited to the tab or window where it was created.
