code block doesn't work

i believe that issue related to highlight.js there's no related distro but i will mention little of my distro information

os	arch	caprin version	instalation method
deepin-linux 15.11	amd64	2.45.0	deb file

tested examples

var s = "JavaScript syntax highlighting";
alert(s);

s = "Python syntax highlighting"
print s

examples resource

result

return simple text not highlighted

i thought it will provide a highlighted syntax not only a bolder borders, if there's no way to do it it's ok i can continue use slack, thanks @sitiom.
