Hey Mark
I’m not a full polyglot developer. I’m especially good at Java and Go. A little bit in Python (because the world blindly trust Python) but as you can see in my article, I felt in a Python edge case.
I’m not good at all in NodeJS.
And ruby? I don’t know from where to start! But if you have the capacity to perform a similar test with Ruby, you can write an additional article to supplement this one!
