  print(tonumber(a) + tonumber(b))
end

mcs (.cs)

      System.Console.WriteLine(int.Parse(tokens[0]) + int.Parse(tokens[1]));
    }
  }
}

node (.js)

var fs = require('fs');
var buf = '';

process.stdin.on('readable', function() {
  var chunk = process.stdin.read();
  if (chunk) buf += chunk.toString();
});

process.stdin.on('end', function() {
  buf.split('
').forEach(function(line) {
    var tokens = line.split(' ').map(function(x) { return parseInt(x); });
    if (tokens.length != 2) return;
    console.log(tokens.reduce(function(a, b) { return a + b; }));
  });
});
