Question 14/50
A developer has two ways to write a function:
Option A:
function Monster() {
This.growl = () => {
Console.log ("Grr!");
}
}
Option B:
function Monster() {};
Monster.prototype.growl =() => {
console.log("Grr!");
}
After deciding on an option, the developer creates 1000 monster objects.
How many growl methods are created with Option A Option B?

Option B:

Recent Comments (The most recent comments are at the top.)
after asking chatGPT here is its answer:
In Option A, a new growl method is created every time a new Monster object is created. This is because the growl method is defined as an arrow function inside the Monster constructor function. So, if the developer creates 1000 Monster objects, there will be 1000 growl methods created.
In Option B, only one growl method is created, which is attached to the Monster prototype. This is because the growl method is defined as a regular function and attached to the Monster prototype object, which is shared by all Monster objects. So, if the developer creates 1000 Monster objects, there will be only one growl method created and shared by all 1000 objects.
Therefore, the number of growl methods created will be:
Option A: 1000
Option B: 1
Answer is A based on my explanation previously. sorry for the confusion
Just to clear things up. If you create 1000 monster object instance using Option A, each of those will get the growl method as a property. Meanwhile, in Option B, growl method is attached to its Monster prototype. only one growl method is created and is shared in all instance.
Answer is B.
I believe the answer should be option B.
Because In JS you can redefine functions. A subsequent function with the same name as another function will overwrite it. Therefore if you create 1000 monster objects you will have only 1 growl method because it gets overwritten by the latest one.
