-
The enumeration order becomes implementation dependent and non-interoperable if:
-
- The delete keyword is never used
- Object.defineProperty() is not used
- If the object inherits enumerable properties
- The object does not have the properties present in the integer array indices
- None of these
Correct Option: C
In computer programming, an enumerated type (also called enumeration or enum) is a data type consisting of a set of named values called elements, members or enumerators of the type. The enumerator names are usually identifiers that behave as constants in the language.
