Presumably other languages with JIT do exactly the same thing?

dtech • Dec 22, 2024 • View on HN

Read the article, this doesn't reduce JIT capabilities at all.

mjwalshe • Oct 9, 2012 • View on HN

Well JIT does have its downside

pjmlp • May 11, 2025 • View on HN

Not necessarly, that is a possible option if you want to keep the JIT around, other one is to AOT compile, 100% straight machine code, like any other compiled language.

JIT can be faster than static compilation.

truth_seeker • Sep 1, 2019 • View on HN

Any proof on this ? Are you talking about any specific JIT engines or all ?

kaba0 • Feb 2, 2021 • View on HN

There are JIT compiled languages as well, that could potentially utilize it

pjmlp • Apr 14, 2018 • View on HN

Any language can have a JIT compiler, that is just an implementation detail.

grishka • Apr 5, 2024 • View on HN

JIT compilation isn't free either.

outworlder • Mar 26, 2016 • View on HN

Still doesn't change much when said language can be JIT'ed.
