I just started learning programming using MarkLogic. I followed documentation, created "sample.sjs" file like in below. https://docs.marklogic.com/guide/jsref/language#id_71272
xdmp.setResponseContentType("text/plain");
"hello"
How should I call this "sample.sjs" to display result in HTML? Or should I better include HTML code inside "sample.sjs" file?
