Javascript classes don't work

[lovettchris]

EcmaScript6/ECMAScript2015 added classes,

class User {
    ref = null;
    constructor(r) {
        this.ref = r;
    }
}

when I try and minify this I get a bunch of errors like:

Error		(Bundler & Minifier) Expected ';'		site.min.js	15

I assume this is not on the radar for this project?
