How to detect which Bootstrap version is used from JavaScript?

Question

I\'ve been looking at the CSS & JavaScript from Bootstrap 3. Nothing is modularized under a common alias. For the JavaScript, it is injected into jQuery\'s prototype...<

Answer 1

As suggested in comments, the only function that seems to be removed in Bootstrap 3 was typehead, even then - there doesn't seem to be a reliable way of detecting which Bootstrap version the site has loaded.

var bsVersion = ( typeof $.fn.typeahead !== 'undefined' ? '2.3.2' : '3.0.0' );
