31 HTML web storage provides two objects for storing data on the client:
32 •window.localStorage - stores data with no expiration date
33 •window.sessionStorage - stores data for one session (data is lost when the browser tab is closed)
34 
35 Before using web storage, check browser support for localStorage and sessionStorage:
36 
37 
38 if (typeof(Storage) !== "undefined") {
39    // Code for localStorage/sessionStorage.
40   }  else {
41    // Sorry! No Web Storage support..
42   }
