localStorage
The localStorage object allows storing key-value pairs in a persistent store. Both keys and values are stored as strings.
On iOS, there is an additional object secureStorage available in the global scope. This is a drop-in replacement for localStorage that keeps data in the encrypted iOS Keychain.
The localStorage is only meant to store relatively short strings. To store larger amounts of data it is recommended to use the FileSystem API.
This object is available in the global namespace. You do not need to import it explicitly.
