Why doesn't gzip work for js on Apache?

Question

JavaScript

Good evening everyone, the thing is, I recently switched to VPS, I started optimizing the site for speed by checking with google page speed. And everything would be fine if damn gzip worked on JS files. I checked through different services, they all give out that gzip does not work on JS. Here is my .htaccess, what could be the problem? all mods are enabled and file types are registered in mime
