But that's them. I want to develop ES6 in my browser natively and offer my app to people with modern browsers. I don't care about those stuck in the past. Why don't the browsers support it? Browsers support WebGL today where i can run advanced 3D graphics in my browsers. Government workers on Netscape 4.7 won't be able to run but still the browsers have that. Why not ES6? Surely webgl is more complex to implement...
