HTML5 offers two new objects for storing data on the client:

LocalStorage – stores data with no time limit

<script type=“text/javascript”>

localStorage.lastname=“ZAG”;

document.write(localStorage.lastname);

</script>

SessionStorage – stores data for one session.The data is deleted when the user closes the browser window.

<script type=“text/javascript”>

sessionStorage.lastname=“ZAG”;

document.write(sessionStorage.lastname);

</script>
