Why does require('intro.js') export an object with just introJs?

[ibc]

var introJs = require('intro.js');

console.log(introJs);

output:

Object { introJs: function(targetElm) }

This has little sense. Why doesn't require('intro.js') directly export the introJs function instead?

So, instead of exports.introJs = introJs; this would be much better to check for window.module and export module.exports = introJs.

Oh wow I was trying to figure this out for an hour now... +1
