Why can't commenting work in sublime 3?

Question

Sublime Text

Just installed sublime (first time, never used before). Here I understand with functions...
Ctrl + / does not work. What could be the reason?

Answer 1

I ran into a similar issue when I used easejs syntax highlighting. In the end, I just gave up on backlighting.

Answer 2

The problem is that the syntax does not describe how to comment (the editor simply does not know how to do it). Check if there is another package with the syntax and, if so, install it (you can find out by the presence of the key punctuation.definition.comment.__package_name__ in the .tmLanguage file).
