This is what I'm talking about. This is not going to happen any time soon. And all attempts to do this only lead to more confusion. It is easier to just learn it and help making it better. The language improved a lot over the last few years so I don't see why replacing an entire ecosystem, browser implementation, libraries, writing transpilers, etc, etc, etc can be any better than just learning to love it as the tool it is.
And let's say in some parallel universe it could be replaced. What is it going to be replaced with? Go? Python? Rust? Everyone has a different opinion so there is no agreement possible. And having any and every language available in the browser is just a wild dream.
So, yes, JavaScript is not perfect. And probably there are a ton of better languages but trying to avoid it and write everything in Go/Clojure/Python/Whatever is ridiculous. That won't happen any time soon. Not using JavaScript is just self inflicting limitations oneself.
