Is there a special meaning for the apostrophe character in html-CodePudding

I saw this code snippet in an article about character encodings.

<html>
<body>
<style type="text/css">p {float: left; padding: 0 15px; margin: 0; font-size: 80%;}</style>
<script type="text/javascript">
for (var i=0; i<128; i  ) document.writeln ((i%32?’:'<p>')   i   ': '   String.fromCharCode (i)   '<br>');
</script>
</body>
</html>

The code is supposed to output all ASCII characters in the specified range. In the for-loop body, in the writeln function, there is an apostrophe after the modulo condition. I don't understand what the apostrophe means. I copied it to my text editor and saved it as a HTML file but it does not render anything on my browser. It produces a syntax error in the console Uncaught SyntaxError: Invalid or unexpected token.

Here is a link to the article - https://www.smashingmagazine.com/2012/06/all-about-unicode-utf8-character-sets/

CodePudding user response：

You can alternatively use single character enclosing tags in place of apostrophe like this. It produces same result as the given in article i.e from 33 to 126.

for (var i=0; i<128; i  ) 
    document.writeln ((i%32?'':'<p>')   i   ': '   
        String.fromCharCode (i)   '<br>');

p {float: left; padding: 0 15px; margin: 0; font-size: 80%;}
