for all WeakMap shims and examples I have seen this to guard the key
as object is basically:
Object.isObject = function isObject() {
return Object(value) === value;
};
why such difference with indeed function ambiguity with your first
example?
We agreed not to treat functions as non-"isObject" objects.
Agreed on Object.type since it's easy to monkey patch while typeof is
already causing my code to look like this
typeof obj != "null" && typeof obj == "object" && !!obj
V8-proofing shows this, yeah. It's a good warning sign in addition to
the sheer runtime incompatibility of changing typeof null to be "null".
So Object.type is the thing to draft. Probably it should return
typeof-like strings with the "null" fix and only that. I do not believe
it should start returning "array" for Array instances, or take other
experimental risks. But we should discuss.
