Quite right, if you're in node, you may as well use util.inherits, especially since it basically does exactly the same thing (plus super_ and constructor):

    exports.inherits = function(ctor, superCtor) {
      ctor.super_ = superCtor;
      ctor.prototype = Object.create(superCtor.prototype, {
        constructor: {
          value: ctor,
          enumerable: false,
          writable: true,
          configurable: true
        }
      });
    };
