I unfortunately need to support Chrome 37 with dash. Natively, there is an error loading the page with the dash core components not loading due to Sets being undefined because they are not introduced until version 38. I did a work around by combining the post from kgr here:
"Error loading dependencies" in IE and older Chrome (51) with the set object defined here:
So my current problem is that this set from this work around works for older browsers but breaks newer browsers. Does anyone have an better idea for a work around to support all versions of Chrome?
