It's most likely a timing issue. The non-REPL code is running within the
same tick, so the socket isn't actually bound until some time later, but
you try and use a method (setBroadcast) that expects a bound socket. The
REPL code works because there is a long enough delay between the
`sock.bind()` and `sock.setBroadcast()` such that the socket is bound by
the time you press enter after typing `sock.setBroadcast()`.
The solution is to wait for the 'listening' event, either explicitly with
`sock.on('listening', ...);` or by passing a callback to `sock.bind();` and
calling your `sock.setBroadcast()`, etc. inside that callback/event handler.
