Ask HN: Help me find an article posted some time ago

I am looking for an article posted some days ago, I would say around 1/2 weeks ago, it was showing some javascript or similar and had a beautifully commented source code, i remember the documentation was on the left and the code on the right. I don't really remember what it was so if someone does it would be amazing. It was not on codepen/jsfiddle etc...

i know it's a long shot but I am can't really find it with hnsearch...

Thanks

EDIT: I found it, if you want to see some nice documented code see OriDomi:
