I honestly don't understand how you could do JS on the backend in 2026. This language and ecosystem are so bad it's ridiculous. Almost all other options (yes, even PHP) are better.
On the browser at least you have the excuse that there's no other option (hoping Wasm will eventually kill JS for good, but we're not there yet).
