Backend development with node.

Knowing how to write native modules is one blog post less on "We rewrote X in Y" on HN frontage.

You might argue why not using something else in first place, well in consulting quite often we have tl adapt to the customer IT stack.

Concrete example deploying into Vercel Functions, and there is a small performance boost required.

Nowadays I would rather push for Go or Rust runtime, but until this year they weren't officially supported, as they were community runtime builds.

In any case, I expect someone doing backend development to actually understand performance, and how to improve it.
