There are not only callbacks, but also event emitters. In you client
"conn.on('data', .." listens to an event emitter, it could be called
multiple times, as long the connection exists. Node exists when you
are no longer waiting for any event, neither event emitter or
callback.

The string being stored to $JS is valid javascript.
len = print('Hello' + ' ' + 'World!' + "\n");
len;
JavaScript programs evaluate to their completion value (the expression

same result, so the `len` global is unnecessary, but

you shouldn't really ever throw, Connect / Express will catch what they can
but not in async callbacks etc. The error handling middleware work just
like regular middleware, so they're executed in sequence, however *usually*

I believe that JS would first finish the onMessage callback function

Since, JS doesn't guarantee that the functions will run at the

Javascript is single threaded. Anything asynchronous that happens, happens
at the end of the execution stack.
In node, asynchronous calls are queued up, then when they are ready to call
the callback, they do so in order. They do not get executed in the middle
of code.
