ChatGPT gave me :
function templater(raw, replacementMap) {
const keys = Object.keys(replacementMap);
const values = Object.values(replacementMap);
return new Function(...keys, "return `" + raw + "`")(...values);
}
new Function(...Object.keys(replacementMap), "return " + raw + "")(...Object.values(replacementMap));

I got a bit further changing the code to use native template literals. But had forgotten that moustache/Hogan includes logic like conditionals and loops
{ "beatles": [ { "firstName": "John", "lastName": "Lennon" }, { "firstName": "Paul", "lastName": "McCartney" }, { "firstName": "George", "lastName": "Harrison" }, { "firstName": "Ringo", "lastName": "Starr" } ], "name": function () { return this.firstName + " " + this.lastName; } }
Template:
{{#beatles}}
-
{{name}} {{/beatles}} Output:
-
John Lennon
-
Paul McCartney
-
George Harrison
-
Ringo Starr
There are 'tagged templates' that allow custom logic,
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals#tagged_templates
but it looks pretty involved. I think from the SPARQL I'd only need to handle one level of lists and exists/not-exists conditionals, but still a lot of work when Hogan/moustache already works. Leave as maybe-later.
