SiteMesh had nothing to do with JS.
MG>more of an alert to JS programmers that for title/body/page.properties
decorations can be handled by sitemesh
MG>struts-plugin
MG><struts>
<bean class="org.apache.struts2.sitemesh.FreeMarkerPageFilter"
static="true" optional="true"/>
<bean class="org.apache.struts2.sitemesh.VelocityPageFilter" static="true"
optional="true"/>
</struts>
MG>FMPageFilter would process page title and body by inserting attrs into
SimpleHash model
model.put("title",page.getTitle());
model.put("body",page.getBody());
model.put("page.properties", new SimpleHash(page.getProperties()));
// finally, render it
template.process(model, res.getWriter());
MG>VPageFilter would insert attrs into velocity Context then render
context.put("title",page.getTitle());
context.put("body",page.getBody());
// finally, render it
PrintWriter writer = res.getWriter();
template.merge(context, writer);
writer.flush();

JavaScript Decorators: What They Are and When to Use
Them<https://www.sitepoint.com/javascript-decorators-what-they-are/>
In its simplest form, a decorator is simply a way of wrapping one piece of code
with another — literally “decorating” it. This is a concept you might well have
heard of previously as ...

MG>the JS coder would say I need transpiler support on my browser for
decorating JS functions is not yet supported
MG>in that case import sitemesh-plugin from struts-2.1.6 and use fm or vm
macros for site decoration
MG>Future considerations:
MG>when ECMAScript gurus incorporate transpiler support for Decorator JS Code
into ECMAscript standard
MG>and chrome,edge,safari,opera and firefox support ECMA standard that has
transpiler support
MG>organisations that supported their-own HTML decorations (Spring/Struts)
MG> can safely deprecate their own decorators and implement JS decorations
