While you may compile dialects into it, you still have to accept the fact that running code in the browser means running JavaScript. So being able to write that, free of any tooling, and free of any strong typing, is a blessing under the circumstances.

By his logic, JS linters are bad because they're tooling that restricts your access to all of Javascript. But linters mean you don't have to read PRs with a fine tooth comb to make sure there's no footguns like using == instead of ===.

Also, you could use that same logic to advocate for writing JVM bytecode directly instead of Java/Kotlin/Scala/Clojure/etc.

The question is really whether tooling pays its way in terms of lower bug rates, code that's easier for coworkers to read, and code that's easier to reason about.
