Removing Stored Data
index.js
When you need to delete a certain value from localStorage, use the removeItem method and provide the key of the item you want to remove. This does not affect other stored data. It is important to always double-check the key you are deleting to avoid removing the wrong data. If the key does not exist, calling removeItem will not cause an error; nothing will happen and the storage remains unchanged. This approach helps you manage persistent storage in a safe and predictable way, especially when working with user data or application settings. Regularly review your storage keys and remove data that is no longer needed to keep your application efficient and secure.
1. Which method removes a single item from localStorage?
2. What happens if you call removeItem with a key that does not exist?
