Комментарии:
1. Особенно , поскольку вы не задали вопрос об этом и не продемонстрировали каких -либо усилий по решению проблемы самостоятельно.
Ответ №1:
Если вы хотите клонировать данные и вернуть новое представление duration , вы можете использовать регулярное выражение для сопоставления часов и минут. Как только у вас будут эти две части информации, вы можете просто умножить часы на 60 и добавить минуты.
Вот разбивка регулярного выражения, которое я использовал:
/ BEGIN EXPRESSION
(?: BEGIN NON-MATCHING GROUP
(d) GROUP 1: HOURS (could add a ' ')
h LITERAL CHAR SEQUENCE
) END NON-MATCHING GROUP
? PRECEDING GROUP IS OPTIONAL
(d ) GROUP 2: MINUTES
min LITERAL CHAR SEQUENCE
/ END EXPRESSION

const filmsWithNewDurations = films.map(film => ({
...film,

1. Очень хорошая разбивка регулярного выражения! Теперь я знаю об этом гораздо больше! Спасибо!
