"JUGGLING ASYNC" answer without BL.

[LautaroCuello]

Hello, guys. I made a frankestein code to resolve this. (And it's bad but if you try various times it works)

var http = require("http");
var url = [process.argv[2], process.argv[3], process.argv[4]];
var responses = [];
var completed_req = 0;

for(var i in url){
    http.get(url[i], function(response){
        var content = "";
        //if(completed_req== url.length){
                response.setEncoding("utf-8");
                response.on("data", function(data){
                    content += data;
                })
                response.on("error", console.error);
                response.on("end", function(end){
                    console.log(content);
                });

    })
};

And the final solution was:

var http = require("http");
var bl = require("bl");
var results = [];
var count = 0;

function printResults(){
    for(var i = 0; i < 3; i++)
        console.log(results[i]);
}

function httpGet(index){
    http.get(process.argv[2 + index], function(response){
        response.pipe(bl(function(err, data){
            if (err)
                return console.error(err);

            results[index] = data.toString();
            count++;

            if(count == 3)
                printResults()
        }))
    })
}

for(var i = 0; i < 3; i++)
    httpGet(i);

And! Surprise it didn't work when I copy it to my file. (I use Spanish language)

I hope it can be fixed (and get the right answer).

EDIT: For some what reason I skipped step 8, then BL now makes sense. I'm gonna close this to fell less stupid.

EDIT 2: After make it works on step 8 without using BL now I need to know how resolve without bl on step 9.

Step 8 results:

var http = require("http");
var url = process.argv[2];

http.get(url, function(response){
    var result = "";
    response.setEncoding("utf-8");
    response.on("data", function(data){
        result += data;
    });
    response.on("error", console.error);
    response.on("end", function(end){
        console.log(result.length);
        console.log(result);
    });
});

Official result:

var http = require("http");
var bl = require("bl");

http.get(process.argv[2], function(response){
    response.pipe(bl(function (err,data){
        if (err)
            return console.error(err);
        data = data.toString();
        console.log(data.length);
        console.log(data);
    }))
})
