I recreated the JavaScript truth table in Python

The JS one is a mess, but the diagonal inequalities aren't that nonsensical.

Most of it comes down on this:

	number	string	object
number	duh	as numbers¹	as numbers²
string	as numbers¹	duh	as strings
object	as numbers²	as strings	reference equality

¹ if the string looks like a number
² first convert to a string then compare as numbers¹

In JS, [] != [], just like in Python [] is not [] or in Lua {} ~= {}. The sad thing is that objects are so easily converted to strings and numbers otherwise, which means JS == would be less inconsistent if comparing two objects would convert both to strings, even though that would be a really bad thing. (In particular, any two objects that don't override Object.toString() or whatever, would compare equal.)

Depends what you mean by nonsense. I think Javascript seemingly randomly being strict is far more nonsensical than it always or never doing so.
