Answer 1

I wrote something that might be easy to use, If anyone has some things to add, feel free to do so.

function getcookie(name = '') {
    let cookies = document.cookie;
    let cookiestore = {};
    
    cookies = cookies.split(";");
    
    if (cookies[0] == "" && cookies[0][0] == undefined) {
        return undefined;
    }
    
    cookies.forEach(function(cookie) {
        cookie = cookie.split(/=(.+)/);
        if (cookie[0].substr(0, 1) == ' ') {
            cookie[0] = cookie[0].substr(1);
        }
        cookiestore[cookie[0]] = cookie[1];
    });
    
    return (name !== '' ? cookiestore[name] : cookiestore);
}

Usage

getcookie() - returns an object with all cookies on the web page.

getcookie('myCookie') - returns the value of the cookie myCookie from the cookie object, otherwise returns undefined if the cookie is empty or not set.

Example

// Have some cookies :-)
document.cookie = "myCookies=delicious";
document.cookie = "myComputer=good";
document.cookie = "myBrowser=RAM hungry";

// Read them
console.log( "My cookies are " + getcookie('myCookie') );
// Outputs: My cookies are delicious

console.log( "My computer is " + getcookie('myComputer') );
// Outputs: My computer is good

console.log( "My browser is " + getcookie('myBrowser') );
// Outputs: My browser is RAM hungry

console.log( getcookie() );
// Outputs: {myCookie: "delicious", myComputer: "good", myBrowser: "RAM hungry"}

// (does cookie exist?)
if (getcookie('hidden_cookie')) {
    console.log('Hidden cookie was found!');
} else {
    console.log('Still no cookie :-(');
}

// (do any cookies exist?)
if (getcookie()) {
    console.log("You've got cookies to eat!");
} else {
    console.log('No cookies for today :-(');
}
