What JavaScript command can be used to get the cookie values from the DOM

Use document.cookie to read cookie values from the page. It returns all accessible cookies as a single string of name=value pairs separated by semicolons, which you can then parse for a specific cookie.

Example

javascript

console.log(document.cookie);

Get one cookie by name

javascript

function getCookie(name) {
  const cookies = document.cookie.split('; ');
  const found = cookies.find(row => row.startsWith(name + '='));
  return found ? found.split('=').slice(1).join('=') : null;
}

Important note

Cookies marked HttpOnly cannot be read from JavaScript, so they will not appear through document.cookie.

TL;DR: the JavaScript command is document.cookie.
