Question

I have an axios call to DELETE and POST my api, and it wasn't rerendering after the calls were fulfilled. It turned out it was because those calls didn't return a new list of objects with the object removed or added. To fix this I put this into my code

Delete:

  case "DELETE_TRIP_REPORTS_FULFILLED": {
    return {
      ...state,
      userTripReports: state.userTripReports.filter(tripReport => tripReport !== action.response), // Filters the deleted trip report out of userTripReports
    }
  }

Post:

  case "POST_TRIP_REPORTS_FULFILLED": {
    return {
      ...state,
      userTripReports: state.userTripReports.reverse().concat(action.response).reverse() // The new trip report must be concatted into the first position
    }
  }

Does this violate any state mutability principals?
