browser wars 1996 deadMicrosoft shipped a second scripting language in the browser and a few intranets used it.
In 2026: Dead outside Internet Explorer, and dead inside it since IE11 turned it off in 2019. Every browser that is not IE has always ignored the block entirely, so the demo below just does nothing.
Where it came from: Microsoft Internet Explorer 3 scripting documentation, 1996. Wikipedia ↗
<script language="VBScript">
Sub GreetButton_OnClick
MsgBox "Hello from VBScript", 64, "Internet Explorer only"
End Sub
Sub Window_OnLoad
Document.Write "<p>This page was written by VBScript.</p>"
End Sub
</script>
<input type="button" name="GreetButton" value="Click me (IE only)">
<!-- And the reason nobody could rely on it -->
<script language="JavaScript">
document.write("<p>JavaScript ran. VBScript almost certainly did not.</p>");
</script>
