Comparison of the differences between localStorage and sessionStorage in js

The content of this article is about the difference and comparison between localStorage and sessionStorage in js. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

1. LocalStorage and sessionStorage are both objects used to store temporary client information.

2. They can only store objects of string type (although other native types of objects can be stored in the specification, but so far no browser has implemented it).

3. The localStorage life cycle is permanent, which means that unless the user clears localStorage information on the UI provided by the browser, this information will exist forever.

4. The sessionStorage life cycle is the current window or tab. Once the window or tab is permanently closed, all data stored through sessionStorage will be cleared.

5. Different browsers cannot share information in localStorage or sessionStorage. Different pages in the same browser can share the same localStorage (the pages belong to the same domain name and port), but sessionStorage information cannot be shared between different pages or tabs. It should be noted here that pages and tabs only refer to top-level windows. If a tab page contains multiple iframe tags and they belong to the same source page, sessionStorage can be shared between them.
