How to use and destroy web storage in Html5?

Answer 1

To set data:
window.localStorage.setItem(key, value);
To get data:
window.localStorage.getItem(key)
To remove data:
window.localStorage.removeItem(key);
To clear all:
window.localStorage.clear();
To get the length of all the data (keys):
window.localStorage.length
To get a key at position `n`:
