Salesforce Exam Javascript Developer I Topic 5 Question 46 Discussion

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 and Option B?
