But you're just trolling (and for something mediocre in the first place, sit down, he said from his lofty perch), so you should stop.
I'm not sure what would make you think I'm trolling, because I'm not. Go was the only language I genuinely knew had a spec on a single page, and I thought other languages don't do that because it's not feasible (and the reason Go can do it is because it's much simpler and has a lot less features).
Now it's interesting to be able to compare the size of the two specs.
Heck, why does this surprise you in the first place? Why do you think it's called ECMAscript?

IIRC, it's about 7 or 8 pages in the printed book.
I could argue that is much easier to write something functional in Go than it is to do the same in Javascript, because the compiler conducts you since the beginning and you can actually get around with Stack Overflow and Google.
Javascript requires a lot more experience, because it can fail in so many ways, it has callbacks everywhere etc.
