Why does typeOf return object instead of array in array data type?

Answer 1

Because Array extends Object prototype

Try this in a console or REPL

Array.prototype.__proto__ === Object.prototype

It outputs 'true'

So based on laws of inheritance an Array *IS AN* Object

As an FYI, typeof can only return six possible results: object, function, string, number, boolean and undefined.

Everything else in JavaScript extends from these base prototypes.
