从 JS 对象中提取特定字段
Extract a particular field from a JS Object
我正在使用 npm app-store-scraper 包从 App Store 获取 1000 个应用程序的应用程序 ID。使用这个 npm 包，我能够生成一个 JS 对象列表，并从 each 对象中，我的目标是获取 "id" 字段 并将其存储在 .csv 文件中。我怎样才能做到这一点？
下面是我正在使用的代码。
var store = require('app-store-scraper');
store.list({
collection: store.collection.TOP_FREE_IPAD,
category: store.category.GAMES_ACTION,
num: 1000
})
.then(console.log)
.catch(console.log);
