не распознан в этом браузере. Если вы хотели отобразить компонент React, начните его имя с заглавной буквы

#typescript #react-native #jestjs #ts-jest

Вопрос:

Похоже, я, возможно, неправильно настроил что-то здесь, где собственные компоненты react помечаются как неродные компоненты из-за оболочки, но ясно, что компоненты уже имеют заглавную букву. Что здесь происходит?
