JavaScript - remove item from localStorage

In this article, we would like to show you how to remove item from localStorage in JavaScript.

Quick solution:

xxxxxxxxxx

localStorage.removeItem('itemKey');

To remove items from localStorage, we use removeItem() method that takes the item key as an argument and removes that key from the storage if it exists. If there is no item with the given key, the method will do nothing.

xxxxxxxxxx

localStorage.removeItem('itemKey');

Note: localStorage is BOM (Browser Object Model) global object so we can also access it using window.localStorage.

As an alternative, you can use delete operator to remove item from the localStorage, however this solution is not recommended.

xxxxxxxxxx

delete localStorage['itemKey'];

​

// or:

​

delete localStorage.itemKey;

We use clear() method to remove all items from the localStorage.

xxxxxxxxxx

localStorage.clear();
