How to use the immutadot.splice function in immutadot

export function emitterTabsReducer(state: Tabs = initialState, action: EmitterTabsActions.All) {
    switch (action.type) {
      case EmitterTabsActions.ADD:
        return push(state, 'tabs', {index: state.tabs.length, name: action.payload.name, emitName: '', emitBody: {}});
      case EmitterTabsActions.REMOVE:
        return splice(state, 'tabs', action.payload.index, 1);
      case EmitterTabsActions.SELECT_TAB:
        return set(state, 'selectedTabIndex', action.payload.index);
      case EmitterTabsActions.CHANGE_EMIT_NAME:
        return set(state, `tabs[${action.payload.tabIndex}].emitName`, action.payload.name);
      case EmitterTabsActions.CHANGE_EMIT_BODY:
        return set(state, `tabs[${action.payload.tabIndex}].emitBody`, action.payload.body);
      case EmitterTabsActions.REMOVE_ALL:
        return cloneDeep(initialState);
      case EmitterTabsActions.CHANGE_STATE:
        return cloneDeep(action.payload);
      default:
        return state;

    }
  }
