A handy utils for modern JS developers

import getWindowObj from './getWindow';
/**
 * @description -- Browses only --
 * In this cookieUtils object:

findCookieByName: Searches for a cookie by name and returns its parsed value.
getCookies: Retrieves all cookies and returns them as an array of parsed objects.
setCookie: Creates or updates a cookie with the specified name, value, and expiration in days. It uses encodeURIComponent for encoding the cookie value.
parseCookie: Splits a cookie string into its name and value and decodes the value.
deleteCookie: Deletes a cookie by setting its expiration date to a past date.

 *
 *@example
 * cookieUtils.setCookie('test', '123', 7);
console.log(cookieUtils.findCookieByName('test'));
console.log(cookieUtils.getCookies());
cookieUtils.deleteCookie('test');
