    You can use a regular expression that matches the URLs and replace them with an empty string using the .replace() method.

      function removeURLs(text) {
    // Regular expression to match URLs
    const urlRegex = /(b(https?|ftp|file)://[-A-Z0-9+&@#/%?=~_|!:,.;]*[-A-Z0-9+&@#/%=~_|])/ig;
    // Replace URLs with an empty string
    return text.replace(urlRegex, '');
  }

    You should definitely use regular expressions.

    You can find the answer of how to create a regular expression for URLs here: What is a good regular expression to match a URL?

    Once you have this regular expression, you can do something like this: (And make sure the regular expression has the g modifier flag to cath all instances)

    var myStr = ...;
const regex = ...;
myStr.replace(regex, "");
