Match the following object properties/methods to their respective descriptions.
Premises:
Returns an array of the enumerable properties found in obj
Returns the value of object as a text string, number, Boolean value, undefined, or null
Returns the value of object as a text string, number, Boolean value, undefined, or null
Returns true if the prop property is enumerable
Returns true if object exists in object obj prototype chain
Returns true if obj is frozen
Returns true if the prop property is enumerable
Returns the value of object as a text string, number, Boolean value, undefined, or null
Returns true if obj is frozen
Returns true if object exists in object obj prototype chain
Returns an array of the enumerable properties found in obj
Returns true if object has the specified property, prop
Defines or modifies the properties, prop , for the object, obj
References the constructor function that creates object
References the prototype of the object, obj
Creates an object using the prototype, proto ; where properties is an optional list of properties added to the object
Returns true if object exists in object obj prototype chain
References the prototype of the object, obj
Returns true if object has the specified property, prop
