What is CORS and how does it affect fetch requests?

CORS stands for Cross-Origin Resource Sharing. It's a security feature that allows or restricts resources requested from another domain.

Can you explain how to enable CORS on a server?

To enable CORS, you can set the Access-Control-Allow-Origin header in your server's response to specify which domains are allowed.

What happens if CORS is not enabled?

If CORS is not enabled, browsers will block requests made from a different origin, leading to errors in your application.

Are there any security risks associated with CORS?

Yes, improperly configured CORS can expose your API to unauthorized access, so it's important to restrict origins carefully.
