Ever tried to fetch data from another website in your web app — and got blocked?
That’s CORS in action!

CORS, or Cross-Origin Resource Sharing, is a security feature built into web browsers.
It controls which websites are allowed to talk to each other.

By default, a website can only request resources from the same origin — that means the same domain, protocol, and port.

If your app needs to call an API from another domain, the server has to say,
‘Hey, it’s cool — I trust this site!’
That’s done by setting the right CORS headers.

No CORS? No access.
But with it? Smooth cross-site communication — and safe too.

So yeah — CORS is the bouncer at the web’s door.
