Лучший и самый эффективный способ программной деструкции определенных свойств из ОГРОМНОГО JSON вложенных объектов и массивов

/ 31 октября 2019

Так как я работаю с SOAP API, который возвращает XML, и мне нужен / нужен JSON после ответа xml2json, это именно то, что я получаю: Ticket! Мне, например, нужно: описание билета, заголовок билета, номер билета ... еще несколько, но для демонстрационных целей достаточно 3

Быть объектом JSON ниже настолько неприятно ... что лучше или лучшеэффективный способ получить то, что мне нужно выше: -описание тикета -титл названия тикета-номер тикета

В JSON вы можете найти объекты с именами: Описание, Название, Номер тикета (все строки)

Я думал о том, чтобы сделать его массивом или массивом, используя Object.entries (JSON)

, а затем выяснить, насколько глубоко этот массив массивов использует рекурсивную функцию.

Может быть, затем попытатьсявыровнять массивы массивов на любую глубину, найденную выше.

Но я все еще продолжаю смешивать массивы и объекты.

ПОМОГИТЕ!

Вы можете создать функцию, которая рекурсивно проходит через объект, и это elements. Если name включен в набор имен, добавьте его в выходной массив 

const flattened =
