The Window sessionStorage object lets you store key/value pairs in the browser.

<!-- html element to place output -->
<p id="my_output"></p>

// store key/value
sessionStorage.setItem('name', 'Johnny');

// read key/value
let my_name = sessionStorage.getItem('name');

// output to the HTML element
document.getElementById('my_output').innerHTML = my_name;

Johnny

Saving the data:

window.sessionStorage.setItem('key', 'value');

// or

sessionStorage.setItem('key', 'value');

Reading the data:

sessionStorage.getItem('key');

Removing the data:

sessionStorage.removeItem('key');

Clearing everything from session storage:

sessionStorage.clear();
