I've been using this:

function read_cookies() {
	let cookies = {}
	for (let item of document.cookie.split(";")) {
		let match = item.match(/^\s*([^]*?)="?([^]*?)"?\s*$/)
		if (match)
			cookies[match[1]] = decodeURIComponent(match[2])
	}
	return cookies
}

Rewrite to work on older browsers / js versions:

Object.fromEntries(document.cookie.split(/; */).map(function(c) {
    var index = c.indexOf("=");     // Find the index of the first equal sign
    var key   = c.slice(0, index);  // Everything upto the index is the key
    var value = c.slice(index + 1); // Everything after the index is the value

    // Return the key and value
    return [ decodeURIComponent(key), decodeURIComponent(value) ];
}));

Object.fromEntries(document.cookie.split('; ').map(v=>v.split(/=(.*)/s).map(decodeURIComponent)))
