+Хранение состояния
+
++ 1.Минусы метода хранения в оперативной памяти в том, что доступ к данным есть только во время одной сессии , 
+  после перезагрузки приложения, доступа к данным уже не будет.
++ 2.Отсутствие масштабируемости.
++ 3.Нет истории изменений
+-----------------------------------------------------------------------------------------------------------------------------
+Переход на json
+
++ 1.После того, как список оперативной памяти изменился на файл проекта, мы получаем доступ к данным хранилища даже после перезапуска приложения, данные не исчезают, а остаются в списке
++ 2.Можно открыть файл и редактировать его вручную
++ 3.Так как json файл является локальным, то при создании копий приложения, у них будут разные файлы tasks.json
+-----------------------------------------------------------------------------------------------------------------------------
+Хранилища задач
+
+Задачи можно хранить в облачных хранилищах:
+
++ Плюсы: Доступ откуда угодно
++ Минусы: Обдачные хранилища зависимы от сторонних ресурсов
+Задачи можно хранить в баазах данныхЖ
+
++ Плюсы: Поддержка транзакций, масштабирование и надежность
++ Минусы: Сложная настройка

+Состояние гонки, это когда два разработчика делают одно и то же в коде и возникает конфликт(данные одного разработчика перезаписывают данные другого.
+Если перенести хранение на базу данных , то решится проблема с гонками, плюс данные лучше защищены и легче масштабировать
