                                    const setCookie = (options) =&gt; {
  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) =&gt; {
  if (document.cookie.length == 0)
    return;

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

  const value =

}

const deleteCookie = (name) =&gt; {
  setCookie({
    name: name,
    value: undefined,

// Example string
setCookie({

  value: 'dude',
});

const username = 
  getCookie('username');


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

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