I have yet to find a better package, when you transpile, debugging always has that funky thing with two different source codes where you wrote one and the other is what is running. And it is not like you can do anything that you can't do in JavaScript, either you have a feature subset, or you ship with a library that the transpiler attached.
You miss the point. The issue isn't whether it's nicer to use a transpiled-to-JS language or JS itself. The issue is that JS as the root is an unfortunate situation, and there are so many other languages that would be superior.
Just look at the history of JavaScript. It does not deserve the attention or human time that it currently gets (compared to other languages, assuming we could all decide simultaneously to replace JavaScript with another language).
I have a hard time justifying using any other dynamically-typed language over JS. And JS' static typing story is pretty mature. And it has cool features like async-everything and a first-class Promise.
So, let's not be too extreme here just because you don't like something. It gets really silly to hear HNers suggest the equivalent of "I don't understand how people own blue cars. They must secretly aspire to drive $myFavoriteColor. Don't they realize how stupid blue looks to me?"
