While `instanceof Array` will not work with an array created in a different realm such as an `iframe` in a webpage, `Array.isArray()` will.

This is because the Array class has a different constructor in each realm, and each `iframe` has its own ream, meaning that the function in the prototype chain will be different, causing `instanceof Array` to fail.

`Array.isArray()` is capable of ignoring this, and should always be used when possible.

It can also survive false positives where an object isn't actually an `Array`, and merely has `Array` in its prototype chain.
