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.
