A POST request using Fetch API is used to send data securely to the server.
POST requests are commonly used for login, registration, and form submission.
When sending data using POST, request options must be provided.
Data is sent using the body property.
After sending the request, the response must be processed.
POST requests do not expose data in the URL, making them more secure than GET requests.
Fetch POST requests are widely used in modern frontend and full-stack development.
