What is the difference between local storage and session storage?

What is the difference between local storage and session storage?

Local storage and session storage are both part of the Web Storage API, but they serve different purposes. Local storage persists even after the browser is closed, while session storage is cleared when the page session ends.

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

Sure! Use local storage for saving user preferences or data that should persist across sessions, like a shopping cart. Use session storage for temporary data that only needs to last for the duration of a page session, like form data.

Are there any size limits for these storage types?

Yes, local storage typically allows around 5-10MB per origin, while session storage has the same limit. However, this can vary by browser.

Is it secure to store sensitive information in local storage?

It's not recommended to store sensitive information in local storage, as it can be accessed by any script on the page, making it vulnerable to XSS attacks.
