Syntax to "bake" a cookie:
document.cookie = "attribute = value"; //Simple case without options
Examples:
document.cookie = "course=IFSC 3300"; //Session-only cookie
document.cookie = "course=IFSC 3300; expires=Thu, 01 Jan 2025 00:00:00 UTC";
document.cookie = "course=IFSC 3300; expires=Thu, 01 Jan 2025 00:00:00 UTC; path=/";
To delete it:
document.cookie = "course=IFSC 3300; expires=Thu, 01 Jan 1970 00:00:00 UTC";
document.cookie = "course=IFSC 3300; expires=Thu, 01 Jan 1970 00:00:00 UTC; path=/";
Now bake your own cookie!
Example code to "taste" a cookie:
document.getElementById('printHere').innerHTML+=document.cookie;
