Why NodeJS says that an Array is an Object? [duplicate]

Question

What is wrong on my code?

let x = ['hello',1]
let y = [2]
let z = {x:"hello",y:2}
console.log("type of x:",typeof x) // expected array!
console.log("type of y:",typeof y) // expected array!
console.log("type of z:",typeof z) // expected object, ok

Result:

type of x: object
type of y: object
type of z: object

oops, sorry polluting! I was thinking in JSON primitives instead of Javascript primitives. — Peter Krauss

Because JavaScript arrays are objects.

You can check whether a value is an array using the Array.isArray() function.
