property Process.stderr

Usage in Deno

import { type Process } from "node:process";

The process.stderr property returns a stream connected tostderr (fd 2). It is a net.Socket (which is a Duplex stream) unless fd 2 refers to a file, in which case it is a Writable stream.

process.stderr differs from other Node.js streams in important ways. See note on process I/O for more information.
