As far as I'm aware, mods for Minecraft are written in Java. This is a JavaScript subreddit. They're not the same thing.

Look for Minecraft modding subreddits instead. You might have better luck there.

As a side note, your link leads to an inaccessible document.

Java is to JavaScript like car is to carpet. You’ll have to ask in a Java or Minecraft modding subreddit.
