Streamline vs node

node.js

function doIt (i, callback) {
  callback(i);
}

var start = new Date();
for (var i = 0; i <= 100000; i++) {
  doIt(i, function (val) {
    if (val === 100000) {
      var end = new Date();
      console.log("done: " + (end - start));
    }
  });
}

streamline_bench.js

function doIt (i, _) {
  return i;
}

var start = new Date();
for (var i = 0; i <= 100000; i++) {
  var result = doIt(i, _);
  if (result === 100000) {
    var end = new Date();
    console.log("done: " + (end - start));
  }
}
