What are the differences between local storage and cookies?

What are the differences between local storage and cookies?

Local storage and cookies are both used to store data in the browser, but they have key differences. Local storage can hold larger amounts of data and persists until explicitly deleted, while cookies are limited in size and have expiration dates.

Can you explain how much data each can store?

Sure! Local storage can store up to 5-10MB of data, depending on the browser, while cookies are limited to about 4KB.

What about security? Are there any differences?

Yes, there are differences. Cookies are sent with every HTTP request, which can expose them to security risks. Local storage is not sent with requests, making it generally more secure, but it can still be accessed by JavaScript.

Which one should I use for my web application?

It depends on your needs. Use local storage for larger, persistent data that doesn't need to be sent to the server. Use cookies for session management or when you need to send data with requests.
