I'm looking at it in OpenOffice, so just for fun, I tell OOo to do a regex-search on
and globally replace that with zilch, thereby wiping out all comment lines.
The result? With comments, Oracle's Core.js file is 140 KB. Without comments: 95 KB. Imagine: almost 50K of comments in a 140K file.
I don't think I've ever seen such well-commented code in any language, ever.
