custom error with clean stack trace

1.js

function createError(msg, status){
  var err = new Error(msg);
  err.status = status;
  
  // uncomment this next line to get a clean stack trace in node.js
  // Error.captureStackTrace(err, createError);
  return err;
}

var err = createError("test", 500);
throw err;

I have used a similar pattern in the past to create specific error types: https://github.com/CentralPing/errors/blob/master/errors.js

They can be very useful when employing a universal error handler to determine programmatically how to issue an error response.
