There are so many definitions of OOP out there, varying between different books, documentation and articles.

    Javascript is generally considered OOP, but classes weren’t widely available till 2017.

    Inheritance isn’t fundamental to OOP, and neither are interfaces. You can have a duck- typed OOP language without inheritance, although I don’t know of any off the top of my head.

    Honestly, the more fundamental thing about OOP is that it’s a programming style built around objects. Sometimes OO languages are class based, or duck typing based, etc. But you’ll always have your data carrying around it’s behavior at runtime.

      JavaScript has been OOP since I can remember due to its prototypal nature. Change something on an inherited prototype, and every descendant also get those changes. And “classes” is just syntax sugar for that prototype mechanism.
