— Understanding HTTP is important though. Otherwise you will end up as php developer wondering why some requests both populate $_GET and $_POST.

So fetch("db.php?sql=select * from TABLE") will ask for "db.php" setting the ?sql somewhere in the PHP (probably the $_GET variable) and you'll have to process the input in the db.php file and echo something out.

— I wonder how you explain telephones to your children 👀

— Also little complicated thing: fetch is async, so this means that it doesn't just return a value, it instead returns a Promise (that is, a wrapper for a value that can either contain it or tell you it is being processed.) To use it easily you'll have to prepend the call with await (that calls the promise and waits until it's done)
