What about this?
console.log("I will goto the STDOUT");
console.error("I will goto the STDERR");
Note: both of these functions automatically add new line to your input.
If you don’t want those newlines appended to your input, do this
process.stdout.write("I will goto the STDOUT")
process.stderr.write("I will goto the STDERR")
Both process.stdout and process.stderr are streams, so you can even pipe a stream into them. See Node.js docs on streams for more info.
