Exploring streams

According to Bjarne Stoustrup in his book, The C++ Programming Language, (third edition):

"Designing and implementing a general input/output facility for a programming language is notoriously difficult... An I/O facility should be easy, convenient, and safe to use; efficient and flexible; and, above all, complete."

It shouldn't surprise anyone that a design team, focused on providing efficient and easy I/O, has delivered such a facility through Node. Through a symmetrical and simple interface, which handles data buffers and stream events so that the implementer does not have to, Node's Stream module is the preferred way to manage asynchronous data streams for both internal modules, and the module's developers will create.
