How to use the cldr-core/defaultContent.json.defaultContent function in cldr-core

let NUMBERS_LOCALES_HASH = glob.sync("*/numbers.json", {
  cwd: path.resolve(CLDR_NUMBERS_DIR, "main")
}).reduce((hash, filename) => {
  hash[path.dirname(filename)] = true
  return hash
}, {})

let CURRENCIES_LOCALES_HASH = glob.sync("*/currencies.json", {
  cwd: path.resolve(CLDR_NUMBERS_DIR, "main")
}).reduce((hash, filename) => {
  hash[path.dirname(filename)] = true
  return hash
}, {})

let DEFAULT_CONTENT_ARRAY = require("cldr-core/defaultContent.json")
    .defaultContent.map((value) => value.replace(/_/g, "-"))

// Some locales that have a `pluralRuleFunction` don't have a `dateFields.json`
// file, and visa versa, so this creates a unique collection of all locales in
// the CLDR for which we need data from.
let ALL_LOCALES_HASH =
    Object.keys(PARENT_LOCALES_HASH)
    .concat(Object.keys(CALENDARS_LOCALES_HASH))
    .concat(Object.keys(NUMBERS_LOCALES_HASH))
    .concat(Object.keys(CURRENCIES_LOCALES_HASH))
    .concat(DEFAULT_CONTENT_ARRAY)
    .sort()
    .reduce((hash, locale) => {
      hash[locale.toLowerCase()] = locale
      return hash
    }, {})
