not to be the “but rust” person, but I’m curious why Rust wasn’t in the test group. it seems to meet all their criteria, though the community was a bit smaller back then.

Go is a perfectly reasonable choice though, and easier to learn on average.

Python is not in the list also, despite them using nodejs.

But when I read the following:

   Based on these criteria, we narrowed our testing languages to C++17, Java, Node.js, and Go. The first three languages were already in use at American Express, whereas Go was not.

What I understand is that they did not really wanted to do a real benchmark but they decided to use Go first, and then they had to setup a kind of "bullshit neutral study" to pretend to leadership that Go was the best choice for all the languages that could fit the job.

Maybe it is the case in the end for them, but it is another subject.

My understanding is that JS running on Node is insanely fast compared to most other interpreted languages. This is because of how much work has been put into the V8 engine, especially the JIT compiler.

Based on this, it’s fair to put Node into a league above languages like Python and Ruby when considering performance.

This might have played a role in their decision to include Node.

Rust crypto libraries were definitely not ready in 2019. I think the story is a bit better today.
