this is the language we were given on the web, not the language we chose

I can't test it right now but I would love to know. Is it true?

Seems to be so, see Exceptional behavior of document.all

Although document.all is also falsy and loosely equal to undefined, it is not undefined. The case of document.all having type "undefined" is classified in the web standards as a "willful violation" of the original ECMAScript standard for web compatibility.

not strictly

typeof x === "undefined" is true.

Then the bastard tries to willingly access x to equate it to undefined, but that can't work since x is undefined and yields a ReferenceError (rendering the third expression moot).

The monks answers of document.all is not applicable since document.all is a live set of data which can be nothing or everything.

Who even introduced document.all? I bet it was microsoft...
