When do uncaught exceptions generate events?

When handlers are registered

When handlers are deregistered

When handler functions are called

When handlers do not have a matching catch clause

Uncaught exceptions generate events, if any handlers are registered. Otherwise, the exception just makes Node print an error and exit.

process.on("uncaughtException", function(e) { console.log(Exception, e); });
