node-through2 3.0.1-2 (i386 binary) in ubuntu focal

 This package provide a tiny wrapper around stream.Transform from
 Node.js library to avoid explicit subclassing noise.
 .
 Inspired by Dominic Tarr's through module in that it's so much easier
 to make a stream out of a function than it is to set up the prototype
 chain properly.

 Node.js is an event-based server-side JavaScript engine.
