Use ES6 in Appcelerator Titanium 6.2.0+

ti.es6.js

class Application {
        
    constructor(cb) { 
        this.window = Ti.UI.createWindow({
            backgroundColor: '#fff'
        });

        var btn = Ti.UI.createButton({
            title: 'Trigger'
        });

        btn.addEventListener('click', function() {
            Ti.API.info('Hello world!');
        });

        this.window.add(btn);
    }
    
    open(cb) {
        this.window.open();
        cb('ES6 rocks!');
    }
}

var app = new Application();
app.open((text) => {
    alert(text);
});

Hi man!

Awesome work, but i have questions about it.

How I configure my Titanium project to use ES6 without use Alloy? Have any how-to to make it working?

Thank you for advance!
