There are two methods findSplitVariable. Second one takes extra parameter (varIdx) that is not used anywhere.

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.

var list = new List<string>() { // Assume some items in the list };

for (var i = 0; i < list.Count; i++)
{
    var item = list[i];
    list.Remove(item);
    
    i--;
}

Simple alternative to List.Clear()

guard let reachability = Reachability(), reachability.isReachable == true else {

}

While this works, it's not immediately readable and creates confusion. Mis-using Swift's control flow. Did not pass code review.

Who needs static float when you can have a constant in a nested struct, as a bonus State state has 0 references in the project
