Redux example mutates data in the store

Improvement description

The Redux example makes data reducer:

action.dataChanges.forEach(([row, column, oldValue, newValue]) => {
        newData[row][column] = newValue;
      });

which mutates initialReduxStoreState and breaks one of the key Reducer Concepts: reducer should not mutate its arguments.

Either fix it, see Redux - Updating an Item in an Array. Or, if it's intentional, describe reasons why the immutability concept is broken and provide the above link how to make it immutable way.

Hi @xmedeko

Thank you for this suggestion. I will add it to our internal repository for further investigation and will update you if we add it to the roadmap.
