CORS, or Cross-Origin Resource Sharing, is a security feature implemented by web browsers to prevent web pages from making requests to a different domain than the one that served the original web page.
The use of CORS is to enable controlled access to resources on a web page that are located on a different domain. This allows web applications to make cross-origin requests for resources such as APIs, fonts, and images.
Without CORS, web pages would be restricted to accessing resources only on their own domain, which would limit the functionality and usefulness of web applications.
CORS is essential for web development because it enables cross-origin communication while preventing security vulnerabilities such as cross-site scripting (XSS) attacks and cross-site request forgery (CSRF) attacks. It does this by enforcing strict security rules that must be met before a browser will allow a web page to make cross-origin requests
