node.js - Creating instance of a class directly from require

I have a class in a seperate file. I need to create an instance of it in another file. I tried this:

var connection = new require('./connection.js')("ef66143e996d");

But this is not working as I wanted. Right now I am using this as a temporary solution: 

var Connection = require('./connection.js'); 
connection = new Connection("ef66143e996d");

Two Questions;

First, why doesn't that work.
Second, how can I accomplish this with a one-liner?

The new keyword applies itself on the first function it comes across. In this case, that happens to be require. Wrapping the statement in parentheses will expose the correct function:

var connection = new (require('./connection.js'))("ef66143e996d");
