How do I create and read a value from cookie?

Question

How can I create and read a value from a cookie in JavaScript?

Answer 1

A cheeky and simple way of reading a cookie could be something like:

let username, id; 
eval(document.cookie); 
console.log(username + ", " + id); // John Doe, 123

This could be used if you know your cookie contains something like: username="John Doe"; id=123;. Note that a string would need quotes in the cookie. Not the recommended way probably, but works for testing/learning.
