Is an infinite loop impossible in nodejs?

Question

For some reason, I am trying to present a simple script that can extract tweets from a given Twitter account and then do something with it (which is not a really important part). Following a friend's advice, I tried to do this in nodejs. He helped me a bit (gave me some code), and I managed to do something. Therefore, if I want to get all the tweets from one user, it works great. But in fact, what I would like is a loop and check for new tweets. But when I convert my code at a simple moment (1) (and change it as needed), it does nothing. So here is my code:

var tweetFetcher = require('./tweetFetcher');
var codeExtractor = require('./codeExtractor');
var open = require('open');
var fs = require('fs');
var filters = [filter1, filter2];
var hasfirstpart = 0;
var code = "";
var tweets;
var i = 0;
while(1){
    tweets = tweetFetcher.getFrom('twitteraccount', function(tweets) {
        console.log(tweets[0]);
        if(tweets[0].indexOf(filters[hasfirstpart]) > -1){
            code += codeExtractor.extract(tweets[0]).substring(3);
            hasfirstpart = (hasfirstpart+1)%2;  
            console.log(code);
        }
        if(hasfirstpart == 0 && code != ""){
            ...
        }
    });
}



var parser = require('cheerio');
var request = require('request');


exports.getFrom = function(username, cb) {
    var url = "http://twitter.com/"+username;

    request(url, function(err, resp, body) {
        var $ = parser.load(body);
        var tweets = [];
        $('.ProfileTweet-text').each(function() {
            tweets.push($(this).text());
        });

        if(typeof cb == 'function') {
            cb(tweets);
        }
    });
}

Do you have an idea why it cannot be wrapped in a loop? Thank you in advance for your reply :)

while (1) node.js -, . - , :

function doThing () {
    tweetFetcher.getFrom('twitteraccount', function(tweets) {
        ...

        doThing();
    });
}
