But does it require ES6? Javascript was quite minimal in the early days. It doesn't need a JIT, in fact I'd prefer it not to be.
The difficult bit isn't the core JavaScript support. There are a dozen engines packaged as libraries that can use for that. The difficult bit is supporting all of the hundreds of DOM APIs.
