Redux store.subscribe() doesn't fire on state changes

QUESTION

Redux store.subscribe() doesn't fire on state changes

Asked 2019-Dec-14 at 07:27

The project structure is the following:

If you are trying to use redux, then I would start here.

Is there any quick or even dirty way for achieving this, for very simple expressions, without eval or other libraries?

Here are some examples:
