Q11. What is Session Storage?
Answer:
The sessionStorage object is equal to the localStorage object, except that it stores the data for only one session. The data is deleted when the user closes the specific browser tab or closes the browser.
Example
<script type="text/javascript">
// Check if the sessionStorage object exists
if(sessionStorage){
// Store data
sessionStorage.setItem("last_name", "Parker");
// Retrieve data
alert("Hi, " + localStorage.getItem("first_name") + " " + sessionStorage.getItem("last_name"));
} else{
alert("Sorry, your browser do not support session storage.");
}
</script>
