REDUX. Is it possible to set one object property to (action.payload) and all others to null?

Question

JavaScript

A question. Is it possible for a state redux object, when calling action. Change one field of the object in accordance with (action.payload), and set all other properties of the object to null.
For example:

case SET_VALUE_FIELD:
      return {
        ...state,
        [action.payload.field]: action.payload.value,
      };

Right now it changes one property, and copies all the rest from the previous state. Right here

..state,

Is it possible to somehow set all other properties equal to, for example, null?

Answer 1

return {
  ...Object.keys(state).reduce((acc, n) => (acc[n] = null, acc), {}),
  [action.payload.field]: action.payload.value,
};
