Dependency Injection in nodejs, yes or no?

# Dependency Injection

I come from a Java background where **DI** is a very good approach to build a solid code base. I am interested to hear what the **nodejs** community thinks about this and if the same logic applies.

## Why DI?
DI makes your code more modular since you pass along your dependencies rather then requiring them.
It also makes _unit testing_ a lot easier since you can just pass in fake representations of your dependencies without having to do some complex mocking.

## Why not?
This is the question I would like to see answered.
