Local Storage : For every HTTP request, the data is not sent back to the server (HTML, images, JavaScript, CSS, etc) reducing the total traffic between client and server. Data will stay until it is manually cleared using settings or through program.

Session Storage : It is similar to local storage; the only difference is data stored in local storage has no expiration time whereas data stored in session storage gets cleared when the page session ends. Session Storage will cleared when the browser is closed
