Question
Which of the following is a method of the Object constructor in JavaScript?
- Object.entries()
- Object.values()
- Object.keys()
- All of the above
Solution
To answer the question of which option is a method of the Object constructor in JavaScript, let's analyze each option:
-
Object.entries(): This method returns an array of a given object's own enumerable property [key, value] pairs. It is indeed a method associated with the Object constructor.
-
Object.values(): This method returns an array of a given object's own enumerable property values. This is also a method associated with the Object constructor.
-
Object.keys(): This method returns an array of a given object's own enumerable property names. It is likewise a method linked to the Object constructor.
-
All of the above: Since all the previous options (Object.entries(), Object.values(), and Object.keys()) are methods of the Object constructor, this option suggests that all of them are valid.
Conclusion
Given that all the listed methods belong to the Object constructor in JavaScript, the correct answer is:
All of the above.
