Use low overhead object heritence in Js (Object.create vs new)...
Use low overhead object heritence in Js (Object.create vs new) the use of XX.prototype = new YY(); Does trigger the constructor of YY without the nead for it. `Object.create` does go around this limitation and target browser that are relatively Old. Cf https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/create for more info It might help to get rid of some logic in constructors that check wether some options are passed in, that were causing errors on noteboko load. Typically `if(element){ }` on Abstract `Cell` constructor.
