Provides access to a W3C Storage interface
var storage = window.localStorage;
The window.localStorage
interface is based on the W3C Web Storage interface. An app can use it to save persistent data using key-value pairs. The window.sessionStorage
interface works the same way, but all data is cleared each time the app closes.
var keyName = window.localStorage.key(0);
window.localStorage.setItem("key", "value");
var value = window.localStorage.getItem("key"); // value is now equal to "value"
window.localStorage.removeItem("key");
window.localStorage.clear();

, rather than accessing keys directly from the storage object, such as window.localStorage.someKey
.
