You can read more about forms in React here. Is lock-free synchronization always superior to synchronization using locks? May feature an array of zero or multiple error messages. Use of PUT vs PATCH methods in REST API real life scenarios. RFC 9110: HTTP Semantics substitutes the term content for payload used in previous RFCs: The terms "payload" and "payload body" have been replaced with "content", to better align with its usage elsewhere (e.g., in field names) and to avoid confusion with frame payloads in HTTP/2 and HTTP/3.
