LocalStorage is not a database in the traditional sense, but a simple key-value pair storage mechanism provided by the browser.
It is used to store a small amount of data on the client, such as user preferences, session information, etc. Unlike traditional databases, LocalStorage does not have complex query languages, indexes or relational models. It simply stores data in the browser in the form of key-value pairs. Therefore, although LocalStorage can replace the functions of a traditional database in some aspects, it is not a complete database system.
localStorage is stored and read on the browser side. The localStorage under each domain name is independent of each other and can usually be used to store some user settings, form data, etc. Compared with traditional cookies, LocalStorage has the advantages of large storage capacity, not participating in network requests, and not subject to cross-domain restrictions, so it is widely used in front-end development. It should be noted that since LocalStorage is a browser-side storage method, users can manually clear the data in LocalStorage at any time.
