May I suggest that either the question or the solution should be changed.
I actually wrote the correct solution and then still had to refer to the solution.js when I couldn't get any output to console without ^D to end the prog and only then it dumps to console.
I realise why now only after reading Max's comments about it only being a 'write' stream.
+1 to the concat docs not being clear to me that you couldn't pipe the stream.
Maybe a step that mentions this and some ideas on how to end it gracefully?

concat-stream is only a writable stream, not a readable one meaning you can only pipe things into it, but it can't be piped anywhere
from stream-adventure.
so i should just print out the stream from concat?
from stream-adventure.
it looks like you are already doing that, but you are also piping concat-stream to process.stdout which isn't something it supports
from stream-adventure.
from within your reverse
function, you could write to stdout like this: process.stdout.write(body);
. However, that doesn't pass the verify step as the last line is piped as null
instead of an empty string. I think the expected output doesn't match the description of the task because the description does say to write it to stdout
, not simply to use console.log
from stream-adventure.
+1 the description of this task could use some work. The docs for concat-stream
are not very useful in this case either :( https://github.com/maxogden/concat-stream
from stream-adventure.
I'm closing this since concat solution was updated to use process.stdout.write
in a2fd01a, the problem description was updated to be more clear about concat-stream
and what return in 6bcb767
Also there will be an exercise about writable streams (#240) for complement the doubts about using that.
