Salesforce Exam CRT-600 Topic 7 Question 38 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?
