Setup

  const characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789_#';
  let result = '';
  for (let i = 0; i < length; i++) {
    result += characters.charAt(Math.floor(Math.random() * characters.length));
  }
  return result;
}

function getRandomInt(max) {
  return Math.floor(Math.random() * max);
}

const filters = [generateRandomString(10), generateRandomString(10), generateRandomString(10), generateRandomString(10), generateRandomString(10), generateRandomString(10), generateRandomString(10)];

	return [filters[getRandomInt(filters.length)], filters[getRandomInt(filters.length)], filters[getRandomInt(filters.length)],];
}

		categories: [filters[getRandomInt(filters.length)], filters[getRandomInt(filters.length)], filters[getRandomInt(filters.length)],]
	};
}

	}
	return {
		articles,
		locale: generateRandomString(5),
		filters: generateRandomFilters(),
	};
}


function getArticlesForFilters(filters, articles) {
	return articles.filter(article => {
		return article.categories.some(categoryFilter => filters.includes(categoryFilter));
	});
}

const testLocale = generateLocaleConfig();
console.log('Total articles:', testLocale.articles.length);
