Delete Cookies in JavaScript

Deleting a cookie stored in a browser using JavaScript is very easy. For example if you have a cookie named token in your browser and want to delete it, all you have to do is provide the cookie name and set it to a past date. This deletes it immediately. You can take a look at cookies in chrome’s developer tools.

function setCookie(name, value, days) {
  var d = new Date();
  d.setTime(d.getTime() + (days * 24 * 60 * 60 * 1000));
  var expires = 'expires=' + d.toUTCString();
  document.cookie = name + '=' + value + ';' + expires + ';path=/';
}

function deleteCookie(name) {
  document.cookie = name + '=;expires=' + new Date(1970, 0, 1).toUTCString() + ';path=/'
}

setCookie('token', 'value here', 1);

deleteCookie('token');
