Javascript would be a simple hybrid of object oriented and functional principles if backward compatibility with old hacks and "robust" use for web page scripting didn't require a host of redundant features, syntactic bizarre special cases and and evil semantic choices: -- comments, iterating objects and arrays, the absurd equality operators and type conversions, and so on.
I'm an old JS dev, having been around from its beginning, and I avoid JS's OOP system of prototypes too (along with the class syntax) and stick to only static closures in object literals. VueJS and TypeScript are also mostly written in that style, so I'm in good company. I'm tickled pink that we're at the point where a dev actually _can_ forget that the OOP system exists, because its a horror show. I learned OOP on a prototype-based system (LambdaMOO) so it's not like it's foreign to me, JS's system is just so full of warts and wats it's not funny.
It's scary how good TS is at inferring the type, it'll even infer an instance of a class from a literal, so the interop with class-based code is almost seamless (almost: just don't try destructuring a "real" object or re-binding `this` on a static closure)
