Need for CORS in Node.js
Node.js applications often serve APIs that need to be consumed by clients running on different origins. Enabling CORS in a Node.js server allows these clients to make requests to the server, even if they originate from different domains. This is crucial for building scalable and interoperable web applications.

Cross-Origin Resource Sharing (CORS) is a fundamental security mechanism implemented by web browsers to prevent unauthorized access to resources on a web page from different origins.
