How to find elements without specific attributes in Cheerio?

const cheerio = require('cheerio');
const html = `
  <div class="content">This div has a class attribute</div>
  <div>This div does not have a class attribute</div>
  <div class="footer">This div also has a class attribute</div>
`;

// Load the HTML content into a Cheerio object
const $ = cheerio.load(html);

// Find all div elements without a class attribute using the :not pseudo-class and the attribute selector
const divsWithoutClass = $('div:not([class])');

// Iterate over each div element without a class attribute and print its text content
divsWithoutClass.each((i, div) => {
    console.log($(div).text());
});

// Output: 
// This div does not have a class attribute
