How to disable connection error output in Chrome console?

Question

JavaScript

I am using socket.io for client and server communication.
It is assumed that the application can work offline.
In this case, socket.io constantly tries to connect and the message is displayed in the console
How can I turn off this message?

Answer 1

Make a check when connecting to the socket, if there is no connection on the socket, then save this state and do not make repeated attempts to connect.

Answer 2

var userName = '<?php echo $row_hear['hear']; ?>';
var tl = new Date(userName + '/01/01 00:00:00');

Answer 3

alert('<?php echo 'something'; ?>');
