Kuhariri State Katika Sehemu ya Mjukuu kwenye React

Tutazame sehemu Product iliyopatikana kwetu katika somo lililopita:

jsxfunction Product({ id, name, cost, isEdit, toggleMode, editProd }) {
  return <div>
    Jina: {
      isEdit
      ? <input value={name} onChange={event => editProd(id, 'name', event)} />
      : <span>{name}</span>
    }
    Gharama: {
      isEdit
      ? <input value={cost} onChange={event => editProd(id, 'cost', event)} />
      : <span>{cost}</span>
    }
    
    <button onClick={() => toggleMode(id)}>
      {isEdit ? 'hifadhi': 'hariri'}
    </button>
  </div>;
}

Ni rahisi kutambua kwamba msimbo wa jina la bidhaa na wa gharama ya bidhaa karibu unafanana. Wacha tutoe msimbo huu kwenye sehemu tofauti ProductField:

jsxfunction ProductField({ id, text, type, isEdit, editProd }) {
  return isEdit
    ? <input value={text} onChange={event => editProd(id, type, event)} />
    : <span>{text}</span>
  ;
}

Wacha tubadilishe sehemu Product:

jsxfunction Product({ id, name, cost, isEdit, toggleMode, editProd }) {
  return <div>
    Jina: <ProductField
      id={id}
      text={name}
      type="name"
      isEdit={isEdit}
      editProd={editProd}
    />,
    
    Gharama: <ProductField
      id={id}
      text={cost}
      type="cost"
      isEdit={isEdit}
      editProd={editProd}
    />
    
    <button onClick={() => toggleMode(id)}>
      {isEdit ? 'hifadhi': 'hariri'}
    </button>
  </div>;
}
