JavaScript pattern for multiple constructors

Question

I need different constructors for my instances. What is a common pattern for that?

Answer 1

Sometimes, default values for parameters is enough for multiple constructors. And when that doesn't suffice, I try to wrap most of the constructor functionality into an init(other-params) function that is called afterwards. Also consider using the factory concept to make an object that can effectively create the other objects you want.
