JavaScript .getItem(key)

The .getItem() method takes a key as an argument and returns the associated value. If the key is not present in the Storage object, it returns null.

The Storage object can be either a localStorage object or a sessionStorage object.

Syntax

localStorage.getItem(keyName)

sessionStorage.getItem(keyName)

The keyName parameter is required and it’s a string containing the name of the key to retrieve the value of.

Note: The Storage.length property can be used to test whether the storage object is empty or not.

Example

Below is a basic example of implementing the .getItem() method to retrieve the value of a local storage item:

localStorage.setItem('userName', 'Luigi');

console.log(localStorage.getItem('userName'));
