Memory consumption of a web application in different programming languages

You probably have your opinion on which programming language to use for a larger project, but imagine you have a very small project, and you want it to consume as little memory as possible.

I did a comparison, creating a web application that just returns the string “Hello, World!” in a bunch of programming languages, put them on docker containers, and used docker stats to measure the memory consumption.

The programs were generated by GPT-4, using whatever http-server library it chose, to avoid my own bias to influence it. Not saying GPT-4 is unbiased, but it’s a different bias. The code is available on GitHub.
