That does not necessarily mean that

  1. “UDF” refers to the class or an instance of it in JScript,

and that

  2. the method is available in JScript.

For this to have a chance to work, you need to have something like

  var UDF = …;

in your JScript code *before* you refer to the identifier “UDF”.  The code 
that you posted does not contain such a line, so for that alone it is hard 
to make even an educated guess what might have gone wrong here.

Also, you have not specified your target/test runtime environment(s).
I presume it is Microsoft Internet Explorer up to including version 11 (as 
Microsoft Edge and other recent browsers do not support ActiveX – the API 
has proven to be a security risk, and the technology is proprietary), but
it could be something else.

Finally, you might want to consider switching to a different approach as 
Mainstream Support for Internet Explorer, and therefore ActiveX, will end 
starting 2018-09-01 CE:

<https://support.microsoft.com/en-us/help/17454/lifecycle-faq-internet-explorer>
<https://support.microsoft.com/en-us/lifecycle/search?alpha=Windows%2010>

I do not think it is necessary to use Visual Basic classes or the JScript 
“VBArray” type here.  More recent ECMAScript implementations support the now 
standards-compliant “Int8Array” type:

<http://www.ecma-international.org/ecma-262/6.0/#sec-typedarray-constructors>

According to MDN, Internet Explorer 10 has “Basic Support” of it:

<https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Int8Array>

So should IE 11.
