TypeError: ats is not a function

[MrNocTV]

I got this issue the first time I tried,

here is the import

require('babel-polyfill');
const ats = require('async-to-sync/module/no-es2017');

here is the code that use ats:

var fallback = function(e) {
    alert('Error: ' + e);
  };

var requests = categories.map(function(subcat) {
    getItemLinksOfCat(url, subcat)
});

var arrAsync = [requestsm, fallback]
ats(arrAsync);

console.log("next code")

and here is the message:
