Object is the value of the property key "Object" of the Global Object .

console.log( window.Object === Object ); // true

Type

Type of Object is a function.

console.log( typeof Object === "function" ); // true

Parent of Object is Function.prototype.

console.log( Reflect.getPrototypeOf ( Object ) === Function.prototype ); // true

Purpose of Object is:

To convert primitive value (such as string, number, boolean) to a object. (by Object(…))
Used as a namespace to hold general purpose methods for working with objects. For example, Object.isExtensible(…).
Holds the property key "prototype". The value of Object.prototype is the root parent object of all standard objects. (so they inherit useful methods.) [see Prototype and Inheritance]
