I've seen a lot of people talking about CORS when their building frontend applications.
What does it stand for and what is its purpose?
Cross-Origin Resource Sharing.

cors header, it will determine if the origin is in its list of locations it accepts requests from. And will fail if the origin is not allowed.
It stands for "Cross-Origin Resource Sharing".
