Skeptical of rewriting JavaScript tools in "faster" languages

> I’ve written a lot of JavaScript. I like JavaScript. And more importantly, I’ve built up a set of skills in understanding, optimizing, and debugging JavaScript that I’m reluctant to give up on.

It's not that hard to do the same for a less terrible language. Choose something markedly different, i.e. a low level language like rust, and you will learn a lot in the process. More so because now you can see and understand the programming world from two different vantage points. Plus, it never hurts to understand what's going on on a lower level, without an interpreter and eco-system abstracting things away so much. This can then feed back into your skills and understanding of JS.

I swear some JS devs will go out of their way to avoid learning anything else, whilst simultaneously and breathlessly espousing that we rewrite everything else in JS.

i swear some non js devs will go to extreme lengths to demonstrate solutions that will never run on another machine instead of writing js

Why would they never run on another machine? It's not that hard to write portable code, and done very often. Nowadays for example, you rarely ever think about whether you're on arm or x86.

If you write non-portal code, there might be an important reason (like writing OS components, which you won't do in JS).

almost every time code doesn’t run on my machine, the root cause is a political disagreement with a c-compiler author three layers below my actual problem.

javascript doesn’t have a compiler is my main point.

Bit rich to complain about that when all the major browsers have just as significant differences, and that’s before we bring node into the equation, let alone talking about a good 30% of websites I visit with any quantity of JS in them are either perpetually broken in some way, or so jank as to be effectively broken.
