What file is localstorage?

localStorage is not a file, but a client-side technology that stores key-value pairs in the browser. Using a simple "key/value" storage model, data can be stored in the user's browser. In order to share data between websites under the same domain name, localStorage is stored in the browser's cache area, usually in a file on the hard drive.

localStorage is not a file, but a client-side technology that stores key-value pairs in the browser.

It uses a simple key/value storage model that can store data in the user's browser to share data between websites under the same domain name. localStorage is stored in the browser's cache area, usually in a file on the hard drive, although the implementation details vary from browser to browser.

LocalStorage functions similarly to cookies, but unlike cookies, localStorage data is stored in the browser and users cannot directly modify or delete the data, so it is more secure and reliable. In addition, localStorage can store large amounts of data (usually several megabytes of data), while cookies have a smaller storage capacity (usually only a few kilobytes of data).

It should be noted that the data stored in localStorage can only be shared between pages under the same domain name. That is to say, if the domain names of two websites are different, they cannot share the data in localStorage. In addition, localStorage can only store string type data. If you want to store complex objects, you need to serialize them into JSON strings for storage and reading.
