Like cookies, local storage stores data on the user’s browser. However, it has a far larger size limit, up to 5MB, and the data stored doesn’t get sent with every HTTP request. This allows websites to store larger amounts of data locally, enhancing performance and providing a more efficient user experience. Moreover, local storage is designed to be more secure and robust. Unlike cookies, local storage data persists until explicitly deleted, either by the user or the website. It doesn’t expire after a session ends, which can be beneficial for saving user preferences or other long-term data.
