What are the differences between cache and session storage?

What are the differences between cache and session storage?

Cache and session storage are both used to store data in the browser, but they serve different purposes. Cache is used to store resources like images and scripts to speed up loading times, while session storage is used to store data for a single session, which is cleared when the tab is closed.

Can you explain how long the data lasts in each?

Sure! Data in cache can last for a longer period, depending on the cache control settings. It can persist even after the browser is closed. In contrast, session storage lasts only for the duration of the page session, meaning it is cleared when the tab or browser is closed.

Are there any size limitations for each?

Yes, there are size limitations. Cache can store larger amounts of data, often several megabytes, while session storage typically has a limit of about 5-10 MB, depending on the browser.

Which one is better for storing user preferences?

For storing user preferences, session storage is often better if you want the data to be temporary and specific to a session. However, if you want the preferences to persist across sessions, then cache or local storage would be more appropriate.
