#2

why semicolon( ; ) when writing a constructor method to define key and properties of class why not a comma(,) in between two properties like normally when we define properties of an object.

class Surgeon {
constructor(name,department){
this._name=name;
this._department=department;
}
}


#3

I think beacause, it is not a javascript object that separates its properties with comma. The constructor acts like a function so everyline could be an independent statement or line of code. If you want you can remove the semicolon.
