What is the difference between localStorage and sessionStorage in JavaScript?

In JavaScript, `localStorage` and `sessionStorage` are two types of web storage that allow websites to store data on the client’s computer. Both provide a storage object that can store key/value pairs beyond page refreshes, but they have different scopes and lifetimes:

### Scope and Lifetime

– localStorage: Data stored in localStorage persists until explicitly deleted. It remains across browser sessions, meaning if a user closes their browser and then reopens it, the data saved in localStorage will still be available. localStorage has no expiration time.

– sessionStorage: Data stored in sessionStorage is limited to the lifespan of the page session. A session lasts until the browser is closed or the session is programmatically cleared. If a user closes a tab or window, all data stored in sessionStorage from that tab or window is wiped.

### Use Cases

– localStorage is used for storing data that needs to persist across sessions. This could include user preferences, themes, and other data that should remain accessible regardless of the browser being closed.

– sessionStorage is best suited for data that should only be retained temporarily during the navigation of a site, such as form inputs on multiple pages of a checkout process.

### Accessibility

– Both localStorage and sessionStorage are accessible from any window or tab running on the same origin (i.e., the same protocol, domain, and port), with one key difference:

– localStorage data is accessible across all windows or tabs with the same origin.
