Firstly, just because someone makes a compile-to-js language doesn't mean they ncesserily "hate" JS ... I mean, it may, but it could also very well mean that they prefer their own language instead of JS, but not hate JS per say.

Also, compare this to the number of people who are just using JS normally worldwide, then we'll have perspective of just how many more people are just fine with JS Vs the people who feel the need to make these.

My guess would be that the number of people who like JS and use just normal JS in their projects is far far greater in number than the people who use compile-to-js solutions. So in comparision to the former, the latter group could be called as 'few'.
