Match HTML Comments
This feature allows you to match all HTML comments within a given HTML string using the provided regular expression.
const htmlCommentRegex = require('html-comment-regex');
const html = '<!-- This is a comment --> <div>Content</div> <!-- Another comment -->';
const comments = html.match(htmlCommentRegex);
console.log(comments); // ['<!-- This is a comment -->', '<!-- Another comment -->']Remove HTML Comments
This feature demonstrates how to remove all HTML comments from a given HTML string by using the regular expression to replace comments with an empty string.
const htmlCommentRegex = require('html-comment-regex');
const html = '<!-- This is a comment --> <div>Content</div> <!-- Another comment -->';
const cleanedHtml = html.replace(htmlCommentRegex, '');
console.log(cleanedHtml); // ' <div>Content</div> 'htmlparser2 is a fast and forgiving HTML/XML parser. It can be used to parse HTML and extract comments, among other elements.

Cheerio is a fast, flexible, and lean implementation of core jQuery designed specifically for the server.
