I just wonder, relatively, how big is the part of the ES6/7 driving community which were the people who hated on CoffeeScript because it required a compilation step (and now they love BabelJS). There will be things which you will always hate about JavaScript, visible, on the surface, and that will never go away. Compiled-to-js languages can hide these. This has been the best part of CoffeeScript, where it really shined, and this will carry over future compiled-to-js languages (PureScript, Elm etc.). Unless it turns out that JS+Flow is actually the best balance between flexibility and safety and the world will reach "singularity".
