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]
console.log ( typeof Object === "function" ); // true
Parent
Parent of Object is Function.prototype.
console.log ( Reflect.getPrototypeOf ( Object ) === Function.prototype ); // true
Purpose
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 ofObject.prototypeis the root parent object of all standard objects. (so they inherit useful methods.) [see JS: Prototype and Inheritance]
