JavaScript Standard Input/Output: Unspecified

  7 206 4.7 Bikeshed
  

Common I/O (stdin/stdout/stderr) module specification #47.

  Console Standard (by whatwg)

  

WHATWG's Console mentions stdout several times, does not mention stdin. Using console.log() in a Native Messaging host does not work, as we are not printing to a TTY. That W.I.P. is not applicable reading stdin at all.
