How to Find Links in JavaScript Using a URL?

To find links in JavaScript using a URL, you can use the Fetch API to retrieve the HTML content of the URL and then use regular expressions to extract the links.

Here’s an example:

let url = "https://www.example.com";

fetch(url)
  .then(response => response.text())
  .then(text => {
    let regex = /<a\s+(?:[^>]*?\s+)?href="([^"]*)"/g;
    let links = [];
    let match;
    while (match = regex.exec(text)) {
      links.push(match[1]);
    }
    console.log(links);
  });

In this example, the code uses the fetch function to retrieve the HTML content of the URL https://www.example.com. The code then uses a regular expression to extract the links from the HTML content and add them to an array links. The array of links is logged using console.log(links).
