If Node.js is spawned with an IPC channel, the process.send() method can be used to send messages to the parent process. Messages will be received as a 'message' event on the parent's ChildProcess object.

If Node.js was not spawned with an IPC channel, process.send will be undefined.

The message goes through serialization and parsing. The resulting message might not be the same as what is originally sent.
