— I see, just closures as private scopes

—

Right yes currently there is a lot of Object.assign and other such object management required along with manually restricting or opening up scopes to share members

— The provided class syntax falls flat when it comes to extending

— I found an example I wrote awhile ago

—

function myClass () {
  var self;
  var myObj = {
    combined: self,
    privates: {
      prop: "Hello World"
    },
    publics: {
      prop: "Sup Bro"
    }
  };
  self = Object.assign({}, myObj.privates, myObj.publics);
  return myObj;
}

— This is my variant of that pattern, not exactly the same and saves some time

— This because js is basically a prototyping object oriented language

— (cb) => Promise.resolve().then(cb)

This? Or I miss understand?

— Have you used Symbols?

— Yep, Symbols are nearly useless

— There is only a very small set of niche use cases for them

— When it comes down to it you will spend just as much effort managing your symbols as you did manually managing references and scope
