I said "dangerous" and not "forbidden for any case". Every rule has some exceptions. It's always dangerous to modify arrays in place, that's why it needs double attention, very nice test coverage, and a lot of edge cases coverage, and a good programming team behind.
In this article there is a kind of "show off some syntax hacks", which IMHO opinion, some are hard to read, some are dangerous, especially for immature programmers, and some are "please read Ecma Script latest changes and don't be so cocky" :D

Haha agreed, especially the second paragraph ;)
The techniques in this article are okay-ish, but I'm not blown away if I may put it like that.
