It is very important to understand both sessionStorage and localStorage as they both have different uses   From MDN      All of your web storage data is contained within two object-like structures inside the browser  sessionStorage and localStorage  The first one persists   data for as long as the browser is open  the data is lost when the browser is   closed  and the second one persists data even after the browser is   closed and then opened again    sessionStorage - Saves data until the browser is closed  the data is deleted when the tab browser is closed   localStorage - Saves data  forever  even after the browser is closed BUT you shouldn t count on the data you store to be there later  the data might get deleted by the browser at any time because of pretty much anything  or deleted by the user  best practice would be to validate that the data is there first  and continue the rest if it is there   or set it up again if its not there   To understand more  read here  localStorage   sessionStorage
