getItem()

Returns a value in the web browser's local storage.

Web browsers can save small amounts of data using the built-in localStorage object. Data stored in localStorage can be retrieved at any point, even after refreshing a page or restarting the browser. Data are stored as key-value pairs.

storeItem() makes it easy to store values in localStorage and getItem() makes it easy to retrieve them.

The first parameter, key, is the name of the value to be stored as a string.

The second parameter, value, is the value to be retrieved a string. For example, calling getItem('size') retrieves the value with the key size.

Note: Sensitive data such as passwords or personal information shouldn't be stored in localStorage.
