socket.on('newMessage', (messageObj) => {
	if (roomNumber === messageObj.roomNumber) {

		console.log("message received:" + messageObj.message);
		$('#messages').append($('<li>').text(messageObj.userName + ' : ' + messageObj.message));

	}
});

socket.in wasn't behaving as advertised (broadcasting to all rooms). I decided to take matters into my own hands.

This developer was trying to force the browser to download a custom image rather than show it inline, so he coded an open reverse proxy and attempted to release it to a production web app. Also, all exceptions are trapped and shown to the user in plaintext in their browser.

My code from 2016 for the hall of shame where I realized today that caseReplace could just return this.replace(o,m=>n.followCase(m)) instead.

final int two_fifty_five_hex = 0xFF
final int two_fifty_five_dec = 255

One is in hex but the other is in decimal! Watch out, make sure you use the correct 255, not the other 255.
