I am using full stack Thymeleaf (spring mvc, security, layout dialect, webflow) in a mid-size web application.
Ok..now that we put so much of code in the html templates
As mentioned Rafal Borowiec to comment block of HTML code you should use
construction (see documentation).
Also it is possible to comment/remove your javascript code using thymeleaf with
/*[-
something to comment -]*/
construction (see documentation). So you can annotate your js code without leaking any information
/*[-
*
* Some information about function.
*
* -]*/
function someFunction() {
console.log('Hello world');
}
