Developers don't understand CORS (2019)

Developers often struggle with CORS (Cross-Origin Resource Sharing), a security feature implemented in web browsers to prevent malicious scripts from making unauthorized requests on behalf of the user. This can lead to issues with API integrations and web applications. To resolve CORS issues, developers should understand the concept of allowed origins, methods, and headers. They should also use the correct HTTP headers, such as Access-Control-Allow-Origin, to enable cross-origin requests. Proper understanding and configuration of CORS is crucial for successful web development.
