How Can I Delete a Cookie Using JavaScript?

Deleting Cookies with JavaScript

In your code, you've created a function called setCookie to set the cookie_name with the provided value. While your createCookie function is defined, it's not utilized in your code.

To remove the cookie effectively, consider incorporating the following approach:

function delete_cookie(name, path, domain) {
  if (get_cookie(name)) {
    document.cookie =
      name +
      "=" +
      ((path) ? ";path=" + path : "") +
      ((domain) ? ";domain=" + domain : "") +
      ";expires=Thu, 01 Jan 1970 00:00:01 GMT";
  }
}

You can define the get_cookie function as follows:

function get_cookie(name) {
  return document.cookie.split(";").some((c) => {
    return c.trim().startsWith(name + "=");
  });
}

By using the delete_cookie function at the start of your program, you can effectively remove the specified cookie by setting its expiration date to a past time.
