Session Storage vs. Local Storage: Are There Any Advantages Beyond Non-Persistence and Tab Scope?

Comparing Session Storage and Local Storage

Session storage and local storage are both technologies used to store data for web applications. They share similar functionality but differ in their persistence and scope. Apart from their non-persisted nature and tab-scoped accessibility, are there any additional advantages of session storage over local storage?

Addressing the Differences

While both local storage and session storage extend the Storage object, their primary distinction lies in the intended non-persistence of session storage.

• Local Storage: Data stored in local storage persists until explicitly deleted. Changes made are preserved across all current and future site visits.
• Session Storage: In contrast, data in session storage is only accessible within the current tab. Any modifications are saved and available until the tab is closed, at which point the stored data is erased.

No Performance or Data Access Benefits

It's important to note that there are no inherent performance or data access benefits to using session storage over local storage. Both technologies offer similar levels of performance and data accessibility.
