I am new to prototypes. I have defined an object literal like this

const obj = {
    name: 'Prashant',
    sayHI(){
        console.log("Hi, I am Prashant");
    }
}

console.log(obj);

Result in console here!!!:

After console logging the object I am getting a property ([[Prototype]]: Object) whose __proto __ property is also referencing to object.prototype.

If obj is an object why it's prototype is also pointing to object.prototype instead of pointing to null and why they both have the same functions?
