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.
