Everything’s an object in Javascript, but as far as i’m aware, declarative programming has taken the javascript world by storm. OOP as we used it in C++ is mostly unnecessary in JS. And given that the object inheritance is totally different between C++ and JS, i don’t know that even if you do know how it all works in JS means it translates well to C++
