nodeJS: Find bad HTPP status

index.js

var fetchUrl = require("fetch").fetchUrl;
var fs = require('fs');

//Domain list from file
var domains = fs.readFileSync('domains.txt').toString().split("\n");

for (i = 0; i < domains.length; i++) { 
	fetchUrl(domains[i], function(error, meta){
		//Without the try catch you encounter crashes due to weird async problmes (at least thats my guess)
		try {
			if (meta.status == 403 || 
			    meta.status == 404 || 
		            meta.status == 500 || 
			    meta.status == 502 || 
			    meta.status == 503 ) {
				    //Outputs only the domains with "bad" Status Codes
				    console.log(meta.finalUrl.toString() + ": "+ meta.status.toString());		
				}
			throw 'excpetion';
		    }
			catch(e) {
		}
	});
