Working with the localStorage data in JavaScript

The setItem method is for saving data. It takes a key as its first parameter and a value as its second parameter. The getItem method is for getting data. It takes one parameter - the key under which this data was stored.

Let's try these methods in practice. First, let's store some string with some key:

javascriptlocalStorage.setItem('key', 'text');

And now retrieve our string from local storage:

javascriptlet str = localStorage.getItem('key');
console.log(str); // shows 'text'
