encoding must be a valid encoding error in process encoding

Question

I have created a simple program for process.stdin and process.stdout. But when i run the program and enter the value for stdout, it shows Error "TypeError: "encoding" must be a valid string encoding". Here is my code .

process.stdin.setEncoding('utf8');
process.stdin.on('data', function(chunk) {
    process.stdout.write("Data >>>>", chunk);
});
process.stdin.on('end', function() {
    process.stderr.write("End!!!");
});

Can anyone tell me what is wrong with program.

This line passes 2 arguments to write:

process.stdout.write("Data >>>>", chunk);

The second argument will be treated as an encoding, not as extra data to write.

Yeah...I would also add to fix use process.stdout.write("Data >>>>" + chunk);
