The getItem() method allows you to access the data stored in the browser’s sessionStorage object.
It accepts only one parameter which is the key and returns the value as a string.
To retrieve the user object from the key stored above:
sessionStorage.getItem('id');
This returns a string with value as;
"{"firstName":"Ramesh","lastName":"Fadatare"}"
To use this value, you would have to convert it back to an object using JSON.parse() method.
JSON.parse(sessionStorage.getItem('id'));
