This means the saved data persists even after the user closes the browser or restarts the computer.
The LlocalStorage is a Window object property, making it a global object that can interact with and manipulate browser windows.
It can be used in combination with other window features and methods.
Data stored in LocalStorage is persistent and this means that if you save some data, close your browser, and then open your application again, all the data will still be recoverable.
However, we may only want to store some data for the duration of a user session.
In this case, we can use the sessionStorage interface.
So, this has all of the same functions that localStorage does but the data we save will automatically be wiped when the user closes the browser tab.
// Storing Data sessionStorage.setItem('name', 'Matt West'); // Retrieving Data var name = sessionStorage.getItem('name'); // Deleting Data sessionStorage.removeItem('name'); // Retrieving an Item Key sessionStorage.key(n); // Clearing the Datastore sessionStorage.clear();
