What is the difference between util.pump(streamA, streamB) and streamA.pipe(streamB)?

Stream.pipe is now the preferred method apparently since 0.3.x so try and use that when possible

There are two significant difference between the two. The first is that the util.pump method can operate on two "stream-like" objects, while the Stream.prototype.pipe assumes that they are stream objects. The second is because of that assumption, the pipe can be chained ( streamA | streamB | streamC ) while the former can't (easily).
