> Like isObject([]) returning true - arrays aren't objects in my mental model. Correct me if I am wrong, but Array factually are JS objects and "[] instanceof Object" is true. Fair enough if that does not fit your mental model, but I would not use any library that treats facts like opinions.
I agree with the author that it’s almost never what you want. But I agree with you that it’s the reality of the platform, ignoring it will cause its own problems. I’d surface the footgun rather than trying to pretend it’s not there: isNonArrayObject and isObjectOrArray, or something like that
Absolutely agree. I also hate that empty arrays are true, which is different from other languages. But I agree that it's better to face the reality of the language than create a function that evaluates [] to false. It trains you a bad habitnand some day that will cause you to introduce a bug.
