How to use the @uifabric/example-data.createListItems function in @uifabric/example-data

constructor(props: {}) {
    super(props);

    this._hasMounted = false;
    // Memoizing this means that given the same parameters, it will return the same array of command objects
    // (performance optimization)
    this._getCommandItems = memoizeFunction(this._getCommandItems);

    this.state = {
      items: createListItems(ITEM_COUNT),
      selection: new Selection({ onSelectionChanged: this._onSelectionChanged }),
      selectionMode: SelectionMode.multiple,
      canSelect: 'all'
    };
    this.state.selection.setItems(this.state.items, false);
  }

openHotKey={KeyCodes.enter}
          />
        )}
      
    );
  }

  private _log(text: string): () => void {
    return (): void => {
      console.log(text);
    };
  }
}

        <p>
          Hover over the <i>key</i> cell of a row item to see the card or use the keyboard to navigate to it by tabbing to a row and hitting
          the right arrow key.
        </p>
        <p>
          When using the keyboard to navigate, open the card with the hotKey and it will automatically focus the first focusable element in
          the card allowing further navigation inside the card. The hotKey is defined by the hotKey prop and is defined as 'enter' in the
          following example.
