"Piping streams" demo: should the ReadableStream remove data?

[ricea]

I think it would be better from an encapsulation perspective if the ReadableStream removed the characters. from the left-hand side. Then the writable stream would only have to add them into the div on the right-hand side.

This would mean that the WritableStream was reusable with other sources of data.

Thanks! Definitely agree. Adjusting now.
