In the chapter "Class basic syntax", in the second example of "what is a class" section, on line 15 of the code it is written in the comment that "there are exactly two methods in the prototype" (constructor, sayHi) which I believe is wrong as constructor is a property referencing the constructor function, right? So shouldn't it be "there are exactly two properties" or maybe "two keys"?
