Split stdin by line with nodejs

splitline.js

#!/usr/bin/env node

process.stdin.resume();
process.stdin.setEncoding('utf8');

var remainder = ''
process.stdin.on('data', function (chunk) {
    var lines = chunk.toString().split('\n');
    lines.unshift(remainder + lines.shift());
    remainder = lines.pop();
    lines.forEach(function(line) {
        process.stdout.write(line);
        process.stdout.write('\n');
    });
});

the last "remainder" is not printed out:

$ echo -n "1111" | nodejs splitline.js
$ echo "1111" | nodejs splitline.js
1111
$

One can add the following to fix it:
16: process.stdin.on('end', function() {process.stdout.write(remainder);});
