        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1,c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
    }
    return null;

setCookie("user_email","bobthegreat@gmail.com",30); //set "user_email" cookie, expires in 30 days
var userEmail=getCookie("user_email");//"bobthegreat@gmail.com"

JavaScript set cookie

const setCookie = (options) => {
  const {
    name,
    value = '',
    path = '/',
    duration = 3600,
  } = options;
  
  const durationMs = duration * 1000;
  const expires =
    new Date(Date.now() + durationMs);

  document.cookie = 
    `${name}=${escape(value)}; expires=${expires.toUTCString()}; path=${path}`;
}

const getCookie = (name, cast = String) => {
  if (document.cookie.length == 0)
    return;

  const match = document
    .cookie
    .match(`${name}=(?<value>[\\w]*);?`);

  if (!match)
    return;

  const value =
    match?.groups?.value ?? '';

  return cast(unescape(value));
}

const cookieExists = (name) => {
  return getCookie(name) !== undefined;
}

const deleteCookie = (name) => {
  setCookie({
    name: name,
    value: undefined,
    duration: -1,
  });
}


// Example string
setCookie({ 
  name: 'username',
  value: 'dude',
});

const username = 
  getCookie('username');


// Example number
setCookie({
  name: 'count',
  value: 100,
  duration: 300, // 300s, 5 minutes
});

const count =
  getCookie('count', parseInt);

deleteCookie('count');
