In modern web development, Cross-Origin Resource Sharing (CORS) plays a critical role in ensuring secure interactions between your frontend and backend components, especially when they are hosted on different domains. Amazon S3 (Simple Storage Service) is a widely used object storage service that often serves static assets for web applications. Enabling CORS in S3 is essential when your web app needs to fetch resources (like images, fonts, JSON, etc.) stored in an S3 bucket from a different domain.
