如何在cheerio nodejs中选择相同的多个元素之一？

const cheerio = require('cheerio');

const html = `
  <div class="item">Item 1</div>
  <div class="item">Item 2</div>
  <div class="item">Item 3</div>
  <div class="item">Item 4</div>
`;

const $ = cheerio.load(html);

// 选择class为item的元素中的第一个或第三个元素
const selectedElements = $('.item:nth-child(1), .item:nth-child(3)');

selectedElements.each((index, element) => {
  console.log($(element).text());
});

Item 1
Item 3
