Deleting All Cookies with JavaScript

Question: How can I programmatically remove all cookies for the current domain using JavaScript?

Answer: JavaScript provides a method to delete all cookies stored by the browser for the current domain. Here's a function that accomplishes this:

function deleteAllCookies() {
    document.cookie.split(';').forEach(cookie => {
        const eqPos = cookie.indexOf('=');
        const name = eqPos > -1 ? cookie.substring(0, eqPos) : cookie;
        document.cookie = name + '=;expires=Thu, 01 Jan 1970 00:00:00 GMT';
    });
}

However, there are limitations associated with this technique:

• HttpOnly Cookies: It cannot delete cookies marked as HttpOnly, which JavaScript is prohibited from accessing.
• Path-Specific Cookies: It also fails to remove cookies with a specific Path value. JavaScript can only delete cookies with matching paths.

By calling the deleteAllCookies() function, you can effectively clear all non-HttpOnly cookies for the current domain without specifying paths.
