Which of the following is a direct way to create a new object that inherits from an existing object's prototype?Explanation:A) Object.create(existingObject)B) new existingObject()C) existingObject.spawn()D) existingObject.extend()
Solution
The direct way to create a new object that inherits from an existing object's prototype is A) Object.create(existingObject).
Here's a step-by-step explanation:
-
The Object.create() method is used in JavaScript to create a new object, using an existing object as the prototype of the newly created object.
-
Object.create() takes the existing object as an argument and returns a new object that inherits all the properties and methods of the existing object.
-
So, if you have an existing object and you want to create a new object that inherits from this existing object's prototype, you can use Object.create(existingObject).
-
The other options B) new existingObject(), C) existingObject.spawn(), and D) existingObject.extend() are not standard ways to directly create a new object that inherits from an existing object's prototype in JavaScript.
