Eclipse Mars Javascript editor: Folding, code formating not working

I have a .js file in eclipse from inside a node / meteor based project.

File looks like this:

import { Meteor } from 'meteor/meteor';
import { HTTP } from 'meteor/http'

function someFunction() {
    //code
};

Meteor.methods({
    //code
});

No options for code folding is shown on the left side in eclipse and also the formatting does not work.

I even installed Nodeclipse and opened the file inside the Nodeclipse editor but same issues remain.

And yes i have Code Folding enabled in the editors options.

Anyone can help?
