Object.getOwnPropertyDescriptors()

The Object.getOwnPropertyDescriptors() method returns all own property descriptors of a given object.

Syntax​

Object.getOwnPropertyDescriptors(obj)

Parameters​

  • obj
    • : The object for which to get all own property descriptors.

Return value​

An object containing all own property descriptors of an object. Might be an empty object, if there are no properties.

Description​

This method permits examination of the precise description of all own properties of an object. A property in JavaScript consists of either a string-valued name or a Symbol and a property descriptor. Further information about property descriptor types and their attributes can be found in Object.defineProperty().

A property descriptor is a record with some of the following attributes:

  • value
    • : The value associated with the property (data descriptors only).
  • writable
    • : true if and only if the value associated with the property may be changed (data descriptors only).
  • get
    • : A function which serves as a getter for the property, or undefined if there is no getter (accessor descriptors only).
  • set
    • : A function which serves as a setter for the property, or undefined if there is no setter (accessor descriptors only).
  • configurable
    • : true if and only if the type of this property descriptor may be changed and if the property may be deleted from the corresponding object.
  • enumerable
    • : true if and only if this property shows up during enumeration of the properties on the corresponding object.
