Why is Array.prototype an array?

Question

I thought that every prototype should be an object.

why?

Array.isArray (Array.prototype) // true

developer.mozilla.org doesn't explain anything

Answer 1

Your assumption that every prototype is Objectwrong.

console.log(String.prototype)
console.log(Number.prototype)
console.log(Boolean.prototype)
console.log(Array.prototype)
console.log(Object.prototype)

Output:

String {}
Number {}
Boolean {}
[]
Object {}

From ECMAScript Language Specification - 15.4.4 Properties of the Array Prototype Object (highlighted by me)

The value of the [[Prototype]] internal property of an Array prototype object is the standard built-in object of the prototype object (15.2.4).

- ; [[]] "", length ( +0) [[DefineOwnProperty]], 15.4.5.1.

Answer 2
