mostrar claves de objeto del prototipo de un objeto en javascript
class Greeter { constructor(message) { this.greeting = message; } greet() { return "Hello, " + this.greeting; } } let greeter = new Greeter("world");

En la consola de google chrome ejecuto esto:

 greeter

Greeter {greeting: 'world'}

 Object.keys(greeter)

Tengo esto que está bien.

['greeting']


 Object.getPrototypeOf(greeter)

{constructor: ƒ, greet: ƒ}

 Object.keys(Object.getPrototypeOf(greeter))

¡Tengo una matriz vacía!

[]

espero que regrese

['greet']

¿Por qué es este comportamiento?
