我有工作代码，并且地图功能中的if语句有一点问题

    const SortableItem = SortableElement(CashItem);
const SortableList = SortableContainer(({items}) => {
  return (
    <div>
      {items.map((cashitem, index) => (
        <SortableItem key={`item-${index}`} 
          index={index} 
          isPayed={cashitem.isPayed}
          date={cashitem.date}
          name={cashitem.name}
          realisticVal={cashitem.realisticVal}
          realisticBalance={cashitem.realisticBalance}
          optimisticBalance={cashitem.optimisticBalance}
          optimisticVal={cashitem.optimisticVal}
          changedName={(event) => this.nameChangedHandler(event, cashitem.id)} 
          isBlocked={(event) => this.handleChangeCheckbox(event, cashitem.id)} 
          delete={(event) => this.removeItem(event, cashitem.id)} 
          addNext={(event) => this.addNext(event, cashitem)} 
          realisticChange={(event) => this.realisticBalanceChangedHandler(event, cashitem.id)}  
          optimisticChange={(event) => this.optimisticBalanceChangedHandler(event, cashitem.id)}  
          dateChangedHandler={(event) => this.dateChangedHandler(event, cashitem.id)}
         />
      ))}
    </div>
  );
});

现在我想要chceck if语句仅在地图Cashitem中具有状态可见时才渲染Cashitems
isVisible已经具有isVisible：true或false我想做这样的事情

 const SortableItem = SortableElement(CashItem);
const SortableList = SortableContainer(({items}) => {
  return (
    <div>
      {items.map((cashitem, index) => (
        if(cashitem.isVisible===true){
          <SortableItem key={`item-${index}`} 
          index={index} 
          isPayed={cashitem.isPayed}
          date={cashitem.date}
          name={cashitem.name}
          realisticVal={cashitem.realisticVal}
          realisticBalance={cashitem.realisticBalance}
          optimisticBalance={cashitem.optimisticBalance}
          optimisticVal={cashitem.optimisticVal}
          changedName={(event) => this.nameChangedHandler(event, cashitem.id)} 
          isBlocked={(event) => this.handleChangeCheckbox(event, cashitem.id)} 
          delete={(event) => this.removeItem(event, cashitem.id)} 
          addNext={(event) => this.addNext(event, cashitem)} 
          realisticChange={(event) => this.realisticBalanceChangedHandler(event, cashitem.id)}  
          optimisticChange={(event) => this.optimisticBalanceChangedHandler(event, cashitem.id)}  
          dateChangedHandler={(event) => this.dateChangedHandler(event, cashitem.id)}
         />
        }

      ))}
    </div>
  );
});
