That's like saying you don't need static typing if you just write better code.

The primary reason to use other languages is not to avoid Javascript, but to use better tools. I use Elm because it has built-in immutability (JS doesn't), a statically-typed ecosystem (JS' is bolted on in a side channel), a single architecture pattern (vs JS' redux/flux/react/angular/etc).

By the time you get static typing, immutability, and an architecture set up in Javascript, you may have taken on a bunch of libraries / moving parts that are more complex that using a different language that comes with all of that out of the box.

Saying I'm just trying to avoid Javascript suggests misunderstanding.
