Keep frozen object as global state

Question

I am playing around with immer.js. Immer.js lock obejct after giving new instance. Is it ok to use this locked object as global state?

windows.initialState = {a: 'a'};
const nextState = produce(initialState , draftState => {
    draftState.a = 'b',
  });

windows.initialState = nextState;

Answer 1

Yes, you can assign and keep the frozen object to the global state. As long as your global object(initial state) is not declared as const. So, Nothing wrongs with this code.
