Else if is working fine, Else is working fine as well, but the initial if statement is not working. Can someone share what this noob is doing wrong - thanks in advance

<code>
<HTML>
<HEAD>
<SCRIPT>
var age = parseInt(prompt("Please enter your age:"))
if (age < 21)
{
alert("Sorry, you are too young to enter")
}
else if (age > 21)
{
alert("Sorry, you are too old to enter")
}
else (age == 21)
{
alert ("Welcome to our exclusive club");
location.href = "http://www.houstonian.com"
}

</SCRIPT>
</HEAD>
<BODY>
</BODY>
</HTML>
</code>

Two other alternatives...

1st based upon posted code...

<HTML>
<HEAD>
<SCRIPT>
var age = parseInt(prompt("Please enter your age:",''));
var tooOldYoung = true;
if (age < 21) {
  alert("Sorry, you are too young to enter");
} else {
  if (age > 21) {
    alert("Sorry, you are too old to enter");
  } else { tooOldYoung = false; }
}
if (!tooOldYoung) {       

  alert ("Welcome to our exclusive club");
  location.href = "http://www.houstonian.com";
}
</SCRIPT>
</HEAD>
<BODY>
</BODY>
</HTML>

2nd with a different approach...

<HTML>
<HEAD>
<SCRIPT>
var age = parseInt(prompt("Please enter your age:",''));
var tooOldYoung = (age < 21) ? -1 : (age > 21) ? 1 : 0;
switch(tooOldYoung) {
  case -1 : alert("Sorry, you are too young to enter"); break;
  case  1 : alert("Sorry, you are too old to enter"); break;
  default : alert ("Welcome to our exclusive club");
            location.href = "http://www.houstonian.com";
            break;
}
</SCRIPT>
</HEAD>
<BODY>
</BODY>
</HTML>

Or a third approach

index.html

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="utf-8" />
	<title>If If Else Else statment</title>
</head>
<body>
	<script type="text/javascript">

	var age = parseInt(prompt("Please enter your age:"), 10);
	if (age === 21) {
		alert("Welcome to our exclusive club");
		location.href = "http://www.houstonian.com";
	} else {
		alert("Sorry, you are too " + (age < 21 ? 'young' : 'old') + " to enter");
	}

</script>
</body>
</html>
