[freeCodeCamp] solution to JUGGLING ASYNC

Here's the official solution in case you want to compare notes:

 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)
