JS: Object Object

Object is the value of the property key "Object" of the global object. [JS: the Global Object]

console.log ( window["Object"] === Object ); // true

Type

Object is a function.

[see JS: Value Types]

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

Parent

Parent of Object is Function.prototype.

// parent of Object object
console.log ( Object.getPrototypeOf ( Object ) === Function.prototype ); // true

Purpose

Purpose of Object is:

1. To convert primitive value (such as string, number, boolean) to a object. (by Object(…))
2. Used as a namespace to hold general purpose methods for working with objects. For example, Object.isExtensible(…).
3. 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 JS: Prototype and Inheritance]
