localStorage.getItem() Method Example

The getItem() method allows you to access the data stored in the browser’s localStorage 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:

localStorage.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(localStorage.getItem('id'));
