What are the best practices for using localStorage in web development?
Some best practices include limiting the amount of data stored, using JSON for data serialization, and handling errors gracefully.
How much data can I store in localStorage?
Most browsers allow around 5-10MB of data per origin in localStorage, but it's best to check specific browser limits.
Is localStorage secure for sensitive information?
No, localStorage is not secure for sensitive information as it can be accessed by any script on the page. Use secure methods for sensitive data.
Can I store objects in localStorage?
Yes, but you need to serialize them to a string format, typically using JSON.stringify() before storing.
What happens if I exceed the storage limit?
If you exceed the storage limit, the browser will throw a QuotaExceededError, and you won't be able to store more data until you free up space.
