How to set cookies correctly?

Question

JavaScript

I put it this way - I look through the devtools,
there is nothing

Answer 1

Judging from the screenshot in the comments, the author is trying to use cookies in the file:// protocol.
They only work in the http / https protocols or in chrome with a special --enable-file-cookies flag.
Run the code through the local server and everything will be ok
