isn't typeof (console.log) "function" and not "object"? by object I meant
an Object object, not 'any arbitrary JS value'. I suppose the distinction
is really blurry, and you would still have to deal with problems like the
object's prototype chain containing callables...

isn't `typeof (console.log)` `"function"` and not `"object"`? by object I meant
an `Object` object, not 'any arbitrary JS value'. I suppose the distinction
is really blurry, and you would still have to deal with problems like the
object's prototype chain containing callables...
