[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)
