It was on HN 2 years ago with some interesting comments: "JSFuck – Write any JavaScript with 6 Characters: []()!+": https://news.ycombinator.com/item?id=6379732

One interesting question was about the "performance impact"? One reply was: "Vanilla I got 225k ops/sec. JSFuck, 4.5 ops/sec. So about 50000 times slower."
