getOwnPropertyDescriptors

getOwnPropertyDescriptors is a static method of the Object object in JavaScript that returns all own property descriptors of a given object. It takes an object as an argument and returns a new object. This new object contains key-value pairs where the keys are the property names of the original object, and the values are the corresponding property descriptors. A property descriptor is an object that describes the characteristics of a property.

These descriptors contain four possible attributes: value, writable, enumerable, and configurable. The value attribute holds the actual data of the property. writable indicates whether the property's value can be changed. enumerable determines if the property will appear during enumeration of properties (e.g., with for...in loops or Object.keys()). configurable specifies whether the property can be deleted or if its attributes can be modified.

getOwnPropertyDescriptors is useful for tasks such as cloning objects with their full property configurations, inspecting property attributes, or creating new objects with identical property setups. It differs from Object.getOwnPropertyNames and Object.getOwnPropertySymbols, which only return the names or symbols of own properties, respectively, without providing their descriptors. This method provides a comprehensive view of an object's own properties and their detailed configurations.
