What HTTP methods do you know? How does PUT differ from PATCH?

Main HTTP methods:

• GET — retrieve data from the server.
• POST — create a new resource.
• PUT — replace the entire resource.
• PATCH — partially update the resource.
• DELETE — delete the resource.
• OPTIONS — find out supported methods.

Difference between PUT and PATCH:

• PUT replaces the entire resource. If some fields are missing in the request body, they will be deleted or reset.
• PATCH updates only the specified fields, leaving others unchanged.

Example:

PUT /users/1
{
  "name": "Ivan",
  "age": 30
}

Replaces the entire user object with id=1.

PATCH /users/1
{
  "age": 31
}

Updates only the age field, other fields remain unchanged.
