Yeah looks extremely compact. I didn't instruct it or told it to use as few lines of code or characters or nothing of the sort.
Not sure why it did that. Its own rationale (which is highly suspect, but the only lead I have) is that it defaults to dense style if it has to write a file in a single go. May be a kernel of truth somewhere in there.
And much code on the web “in production” is minimized.
minified is fewer tokens than the human-readable version that we would write. It only really makes sense to write in minified js - it's also where alot of code in the wild is since every production site minifies their js which is then consumed by training.
