Wrong term used in class article

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"?

Open the linked “Class basic syntax” article and inspect the second example in the “what is a class” section, especially line 15. Check the terminology used for the prototype entries, update the comment if needed, and confirm the example describes the class structure accurately.
