modernizr/src/mStyle.js

Modernizr is a JavaScript library that detects HTML5 and CSS3 features in the user’s browser.

define(['Modernizr', 'modElem'], function(Modernizr, modElem) {
  var mStyle = {
    style: modElem.elem.style
  };

  // kill ref for gc, must happen before mod.elem is removed, so we unshift on to
  // the front of the queue.
  Modernizr._q.unshift(function() {
    delete mStyle.style;
  });

  return mStyle;
});
