Using SSJS to dynamically build landing page content

Question

How would this (or does this) translate to SSJS? This would be part of the HTML body of a landing page.

%%[IF @var > 1 THEN]%%
Show this content
%%[ELSE]%%
Show that content
%%[ENDIF]%%

Answer 1

Something like this:

<script type="text/javascript" runat="server">

Platform.Load("core", "1.1.1");

var var1 = Variable.GetValue("@var");  // or whatever

if (var1 > 1) {
  Write("Show this content");
} else {
  Write("Show that content");
}
</script>

I have an example here that shows a mixture of AMPScript and SSJS.

Also this official documentation is helpful: Server-Side JavaScript
