In principle, you could serve different files to different browsers:

– Browser supports ES6 => serve an ES6 .js file
– Otherwise => compile ES6 to ES5 (or ES3)

What is the best way to do this?

– Browsers tell servers their level of ECMAScript support?
– You can do a feature detection in JS and then load modules conditionally? But 
that seems like a more complicated solution. I’m not even sure how I would 
implement the detection part.
