JavaScript is fast enough (don't rewrite your code)

Frankly, not having web devs touch my native app code is a feature

33:12 V8 is written is C++ and single-handedly turned what it used to be a meme language to a powerhouse today. JavaScript IS built on top of other languages. I get the point you're trying to make but I think the fundamental problem imo is JavaScript devs want everyone else to use JavaScript just because they don't want to learn another language.

The TypeScript compiler is substantially faster as a Go program. Some things are just worth being rewritten in faster languages, especially once the exploratory phase has solidified.

I dont rewrite it for performance i rewrite it for job security

As a PHP developer (12 years + 5 years as hobby) and TS/JS developer (5 years) i learned one important thing: I give a shit about what other think about the language i use, as long as i get shit done and like it while doing.

CLI tools should be written in compiled languages like Rust, Go, Zig, C, C++ always, no only because they are faster and and consume fewer resources, a single binary executable is way more convenient that something that needs a runtime installed

So you’re telling me I need to convert my conversion of JS to Rust back to JS again??

First line: sunk-cost fallacy

What wasn't mentioned at all is that JS uses a lot more memory. Just because of the way it is written. Compiled languages will usually be faster. And unless you hit serious skill issues, they will have a significantly lower memory footprint. Also startup time is better.
