Who would use that kind of type coercion? Who? I want to see his face.

I take this as less of a “I can’t use this intuitive feature reliably” thing and more of a “the truth table will bite you in the ass when you least expect it and/or make a mistake” thing.

Just use a formatter. It’ll show you that the second one is two statements:
{}(the empty block)+[]coerce an empty array to a number:new Number(new Array())
I totally get that: use the right tools and you’ll be okay. This applies to many technologies in this space.
With respect, I still take this advice like hearing “look out for rattlesnakes if you’re hiking there.” It might be safer to just hike where there are no rattlesnakes, instead.
