node.js measure response time with multiple requests

Is there a way to send multiple requests in a loop, and measure the time of each request? In python I'd do:

import requests
import time
for i in range(100):
        start = time.time()
        r = requests.get("http://localhost:80")
        end = time.time()
        total_ms = 1000 * (end - start)
        print("%.2f\n" % total_ms)

In node.js I tried:

var request = require('request');  
for(var i=0;i<100;i++){
    start = Date.now();
    request.get('http://localhost:80/', function () {
        end = Date.now();
        console.log(end-start);
    })
}

But obviously it doesn't give me what I need. Is there something I'm missing?

As for why I'm using node: I seem to get some random response spikes on our servers and I'd like to test it with something different than python and bash curls.

If you really want to do this in nodejs here is an example:

var request = require('request');
var moment = require('moment');

    function makeRequest() {
        var startDate = moment();
        request('http://localhost', function (error,response,body) {
            var endDate = moment();
            console.log('Request took: ' + endDate.diff(startDate) + ' ms.');

        });
    }

    for(var i = 0; i < 100; i++){
        makeRequest();
    }

But I'd rather suggest to use stress load tools for such purpose like JMeter.
