send(operation, ?: headers)

Feature	Send the signed operation to the RPC node for broadcasting to the network. Note: Even if the response data is received successfully, it does not guarantee that the operation will be processed. Always check the operation's facthash to see if the operation was processed.
Parameters	HintedObject | Operation<Fact> signed operation, null | object http header (optional)
Return Value	object OperationResponse

[OperationResponse’s structure ]

{
   response: SuccessResponse || ErrorResponse,
   _api: api address,
   _delegateIP: delegateIP,
} 

example

// Make any raw operation you want to send
const rawOperation = mitum.currency.transfer(sender, receiver, currencyID, amount);
// Add signature to the rawOperation
const signedOperation = mitum.operation.sign(privatekey, op);

// Note: an asynchronous request.
const sendOperation = async () => {
  const info = await mitum.operation.send(signedOperation);
  console.log(info.response);
};
sendOperation();

// output (If sending is successful)
