Checking returned data from php file with equal sign and get () method jquery

I have this:

$(document).ready(function() {

$.get('getturn.php', function(data){
    if (data!=='4') { alert ('  change'); }
    if (data=='4') { alert ('no change');}
    });
});

getturn.php echoes 4 if the turn is equal to a session id, and it echoes the turn number if otherwise. The getturn.php does as it should, it echoes 4 or a number like 0,1,2,3; however when I get the data like seen above from a different file, and check if it equals to 4, I can't get the correct answer... What am I doing wrong? I thought we could check if the output was yes with data=='yes' ? but we can't check numbers with data=='4'?

if understand your problem correctly, this will help: 

data = parseInt(data);
if (!isNaN(data)) {
  if (data != 4) { ... }
  if (data == 4) { ... }
}

just convert "data" variable to numeric value(e.g. integer in this case)

Have you done an alert(data); to see what is returned?

I think you should try this slight modification:

if (data == '4') { alert ('no change');}
            else { alert ('  change'); }

Based on this answer: How do the PHP equality (== double equals) and identity (=== triple equals) comparison operators differ?
