Yeah they do say it ' s prototypical inheritance but the word inheritance there is further misleading . In reality it ' s method delegation . I ' m unsure if Java has delegate methods C # does . I think we need to stop treating Java as the gold standard . Inheritance can be implemented differently than in Java and still be inheritance . The languages Python , Ruby and Smalltalk , for example , all claim to have inheritance in the official docs , yet all implement that inheritance using delegation , just like in JavaScript . <| sep |> hows the comfort on them ? I ' m looking for something I can wear for a few hours on endalso whats the difference between open and closed back ?
