У этого кода две проблемы.

Первая заключается в том, что это очень неэффективно: компонент (и его дочерние элементы) должны перерисовываться между каждым вызовом `set` в цепочке. В приведенном выше примере, в худшем случае (`setCard` → рендер → `setGoldCardCount` → рендер → `setRound` → рендер → `setIsGameOver` → рендер) происходят три ненужные перерисовки дерева.

Даже если это кажется быстрым, с течением времени, при росте вашего кода, вы столкнетесь с ситуациями, когда созданная вами "цепочка" не соответствует требованиям. Представьте, что нужно добавить возможность просматривать историю ходов игры. Этого можно было бы добиться, обновляя каждую переменную состояния до прошлого значения. Однако установка состояния `card` на значение из рендера снова запустит цепочку эффектов и изменит отображаемые данные. Такой код часто является очень хрупким.

В этом случае лучше вычислять то, что можно, во время рендеринга, и корректировать состояние в обработчике событий:
