Not sure what to make of this research. It's not like I can switch out JS in favor of these other languages (many of which are compiled binaries) in my web apps. The performance of for example web servers written in the different languages entirely would seem more interesting to compare.

The JS/TS comparison was directly fishy. I found no mention in the paper of how they managed to "run" the tasks in Typescript, which AFAIK is not possible, or at least not how one would do it in a real life.
