Hacky code to delete all records in a Route53 zone using the aws-sdk module

delete_all.js

var _ = require('lodash')
  , async = require('async')
  , AWS = require('aws-sdk')
  , route53 = new AWS.Route53({apiVersion: '2013-04-01'});
var allRecords = [];
var IsTruncated = true;
var NextRecordName = "";

var listParams = {
  HostedZoneId: zoneId
};
async.whilst(function(){
