JavaScript local storage is a feature that allows developers to store data on a user’s browser.
This data is persistent and remains even after the user closes the browser.
Although, this feature is extremely useful, there may come a time when you need to clear the local storage to free up space or simply because the data is no longer needed.
In this Javascript tutorial, we’ll go through the process of clearing local storage using JavaScript.
Understanding the localStorage Object
The local storage is stored on the user’s browser and can be accessed using the localStorage object in JavaScript.
This object is a property of the window object and can be used to set, retrieve and delete items from the local storage.
Clearing Local Storage using the clear() Method
The easiest way to clear local storage is by using the clear() method.
The clear() method is a method of the localStorage object that deletes all items from the local storage.
The method can be called as follows:
localStorage.clear();
Once this method is called, all items in the local storage will be deleted.
Clearing Specific Items from Local Storage
In case you don’t want to delete all items in the local storage, you can choose to delete specific items instead.
You can do this by using the removeItem() method.
The removeItem() method takes the key of the item you want to delete as a parameter.
For example:
localStorage.removeItem('key');Replace the “key” with the actual key of the item you want to delete.
Conclusion
In this Javascript tutorial, we learned how to clear local storage in JavaScript.
Whether you want to delete all items or specific items, the clear() method and the removeItem() method are both easy to use and provide a quick solution.
