[Kotlin for JavaScript](https://kotlinlang.org/docs/js-overview.html)

The current implementation of Kotlin/JS targets [ES5](https://www.ecma-international.org/ecma-262/5.1/).

I don’t like es5. I have clone [kotlinx.coroutines](https://github.com/Kotlin/kotlinx.coroutines). now [kotlinx-coroutines-core.js](https://www.npmjs.com/package/kotlinx-coroutines-core?activeTab=code) is also es5.

how to build ecmascript latest version by myself?
