Фильтрация JSON по ключу

1

Является ли их способом, где я могу отфильтровать json по имени и именам дочерних узлов и построить новый выход JSON. Поскольку это длинный JSON, у меня он есть здесь

https://gist.githubusercontent.com/senthilthyagarajan/4fd48ebfff70c699ad90cea651b80f42/raw/cd06974c8dd96a5bd6a706ea8ed5f13a8e65f970/drill.json

Из этого выше JSON я хочу отфильтровать и построить ниже JSON:

Теперь вы можете сделать следующее:

result = data.children
    .filter(o => o.name === 'Age')
    .map(o => Object.assign(
        {},
        o,
        { children: o.children.filter(p => ['Female', 'Male'].includes(p.name)) }
    ));

    includes аккуратно, но, к сожалению , не работает во всех браузерах

    Это все еще работает в большем количестве браузеров, чем функции стрелок

Конечно

newJson = oldJson
           .filter( obj => ["Raised","Old Fashioned"].indexOf(obj.name) !== -1 )
           .map( obj => obj.topping )

Это даст вам массив "пополнения" из raised и old fashioned объектов.
